Angular JS - ng-repeat错误

I do not speak English very well, so I apologize in advance for my misspellings

I am creating a user administration page on a site already developed with angular js but it is the first time that i'm using it and I can not figure out the error
When I click on the list on the index.html page to be sent back to the page amministrazione2.html where "should" start the script to get the data from the db and insert them in the table, but the video show

<tbody> <!-- ngRepeat: prezzo in prezzi --> <t/ body> 


instead of my data


this is the index.html, where there is a list on the left and evry item redirect to a .html page

<!DOCTYPE html>
<html ng-app="sin...">
  <head></head>
<body>
    <div class="left_col scroll-view">
            <div ng-include="'includes/header.html'"></div>
            </div>
    </div>
    <div ng-include="'includes/footer.html'"></div>
    </div>
    <script src="//code.angularjs.org/1.5.7/angular.js"></script>
    <script src="//code.angularjs.org/1.5.7/angular-route.js"></script>
    <script src="//code.angularjs.org/1.5.7/angular-cookies.js"></script>
    <script src="//code.angularjs.org/1.5.7/angular-messages.js"></script>

    <script src="js/app.js"></script>

    <script src="modules/amministrazione2/controllers.js"></script>

</body>
</html>

this is the header where there are the element on the left list

<div id="sidebar-menu" class="main_menu_side hidden-print main_menu">

   <div class="menu_section">
     <li>
       <a href="#/amministrazione2">
          <i class="fa fa-cog infospan"></i> Amministrazione2 <span class="fa fa-chevron-right"></span></a>
     </li>
   </div>
</div>

this is the file app.js where there are the declaretions of the angular module

'use strict';

// declare modules
angular.module('Ammi', []);
angular.module('Amministrazione', []);
angular.module('Authentication', []);
angular.module('Home', []);
angular.module('Fornitore', []);
angular.module('Cantiere', []);
angular.module('Prezziario', []);
angular.module('Calendar', []);
angular.module('Computo', []);
angular.module('Forniture', []);
angular.module('Listino', []);
angular.module('Sal', []);



angular.module('sin...', [
    'Amministrazione',
    'Ammi',
    'Authentication',
    'Home',
    'Fornitore',
    'Cantiere',
    'Prezziario',
    'Calendar',
    'Computo',
    'Forniture',
    'Listino',
    'Sal',
    'ngRoute',
    'ngCookies',
    'ngMessages',
    'smart-table'
])

.config(['$routeProvider', function ($routeProvider) {

    $routeProvider
        .when('/amministrazione2', {
            controller: 'AmmiController',
            templateUrl:  'modules/amministrazione2/views/amministrazione2.html',
            hideMenus: true
        })
        .when('/', {
            controller: 'HomeController',
            templateUrl: 'modules/home/views/home.html'
        })

        .otherwise({ redirectTo: '/login' });
}])

this is my php file for search the user information on db

<?php
    require_once '../includes/dbconnector.php';

    $sql = "SELECT a.id_utente, a.id_ruolo, a.nome, a.cognome, a.comune, a.indirizzo, a.cap, a.telefono1, a.telefono2, a.email, a.fax, a.note, a.user, a.password, a.calendario FROM `sal_t_utente` a ORDER BY a.id_utente";
    // use prepared statements, even if not strictly required is good practice
    $stmt = $conn->prepare( $sql );

    // execute the query
    $stmt->execute();

    // fetch the results into an array
    $result = $stmt->fetchAll( PDO::FETCH_ASSOC );

    $json = json_encode($result);

    return $json;
}
?>

this is the angular controller the i've create for insert and modify the data on the table

'use strict';

angular.module('Ammi').controller('AmmiController',
    ['$scope', '$rootScope', '$location','$http',
    function ($scope, $rootScope, $location, $http) {
        $scope.selectedPrezzo = '';

       $scope.getPrezzi = function()
       {
           $http.get('./api/amministrazione2/ricerca.php').
                success(function(data) {
                    $scope.prezzi = data;
                    $scope.prezziCollection= data;
                });
       };

       $scope.editPrezzo = function(prezzo)
       {
            $scope.selectedPrezzo = prezzo;
       };

       $scope.salvaPrezzo = function(prezzo)
       {
            $http.post('./api/amministrazione2/aggiorna.php', {
                'id_utente' : prezzo.id_utente, 
                'id_ruolo' : prezzo.id_ruolo,
                'nome' : prezzo.nome,
                'cognome' : prezzo.cognome,
                'comune' : prezzo.comune, 
                'indirizzo' : prezzo.indirizzo,
                'cap' : prezzo.cap,
                'telefono1' : prezzo.telefono1, 
                'telefono2' : prezzo.telefono2,
                'email' : prezzo.email,
                'fax' : prezzo.fax, 
                'note' : prezzo.note,
                'user' : prezzo.user,
                'password' : prezzo.password,
                'calendario' : prezzo.calendario
                }
                ).success(function (data, status, headers, config) {
                    $scope.resetPrezzo();
                });
       };
       $scope.resetPrezzo = function()
       {
            $scope.getPrezzi();
            $scope.selectedPrezzo = '';
       };

       $scope.go = function ( path ) {
          $location.path( path );
        };  

    }]);

this is the amministrazioni2.html that show the user information

    <div ng-controller="getPrezzi" >

in the end this is what i see on the site

<div ng-view="" class="ng-scope">
