React Ajax和jsx

My array that I filled with my ajax request result will not appears in my react components unordered list.

When I do a console.log of the array I get:

[] 0 : "Career"

1 : "Middle College for Technology Careers"

2 : "Careers New Zealand"

3 : "Careers for Veterans 200"

4 : "Northside Health Careers High School"

5 : "Barbie's careers"

6 : "Edward M. Kennedy Academy for Health Careers"

7 : "The Careers Group, University of London"

8 : "Careers advisor"

9 : "Careers advisory service"

length : 10

proto : Array[0]

When I call this array inside my react component it does not render. Here is my code below.

HTML

<div id="content"></div>

JS

  //array that the titles will be loaded into
  var response = [];

  $.ajax({
    // request type ( GET or POST )
  type: "GET",

    // the URL to which the request is sent
  url: "https://en.wikipedia.org/w/api.php?",

    // data to be sent to the server
  data: { action:'query', format:'json', list: 'search', srsearch: 'careers', srwhat: 'text', srprop: 'timestamp', continue: ''},

    // The type of data that you're expecting back from the server
dataType: 'jsonp',
crossDomain : true,
// Function to be called if the request succeeds
success: function( jsondata ){

for(var i = 0; i < jsondata.query.search.length; i++){
    //console.log( jsondata.query.search[i].title );
  //pushes each result into the array named list
  response.push(jsondata.query.search[i].title);
}

}
});



 console.log(response)


var App = React.createClass({
render: function(){
//var title = list;
return(
  <div>
  <h1>Hello World</h1>
  <p>The world is full of oppurtunity</p>
    <ul>
      <li>{response[0]}</li>
      <li>Freedom</li>
      <li>Lozve</li>
      <li>Money</li>
    </ul>
    </div>
    );
  }
  });

   ReactDOM.render(<App/>, document.getElementById("content"));

Here is a link to my code pen where all my code is, http://codepen.io/vhall_io/pen/vKQrQN/ . I inserted response[0] into the first li tag and it will not render. Please help me render this.

You have to update state. It wont render is you are adding it to variable. as it is ajax call so your html render first
