CakePHP AppExceptionHandler和视图

I checked this question and this cookbook section.
I created such code and made this steps:

In app/Config/core.php

Configure::write('Exception.handler', 'AppExceptionHandler::handle');

In app/Config/bootstrap.php

App::uses('AppExceptionHandler', 'Lib');

In app/Lib/AppExceptionHandler.php

class AppExceptionHandler {
    public static function handle($error) {
        $errorCode = $error->getCode();
        if ($errorCode == 404) {
            header("HTTP/1.0 404 Not Found");
        } elseif ($errorCode == 500) {
            header("HTTP/1.0 500 Internal Server Error");
        }

        echo "here is something is wrong";
    }
}

Everything works fine except the rendering part.
To this time I can only write "something is wrong" but I can't make it viewed inside a view file.

Inside "App/Controller" folder I have "ErrorsController.php".
I need to run ErrorsController when I get an exception. So I will render inside that controller's view files.

1. How can I redirect user to ErrorsController ? Of course I can make it with redirect command. But when I redirect user to ErrorsController::index() function and when I send 404 headers inside ErrorsController, I am redirected to handler page again.
2. Where should I set response headers ? Should I set it inside ErrorsController or from handler ?

Edit:

class ErrorsController extends AppController {
    function beforeFilter() {
        if ( isset($this->request->params['pass'][0]) ) {
             if ($this->request->params['pass'][0] == "404") {
                $this->response->statusCode('404');
            }
        }
    }


    public function index($typeOfError) {
        echo "here I am $typeOfError";
    }
}

When I enter to example.com/errors/index/404 the output is "here is something is wrong" but I need it to be "here I am 404". Because when I enter to ErrorsController's action and send 404 header, I am redirected to AppHandler's handle. So how can I render my own view?

This problem is still exists..
