Rertieve JSON encode in "calendar-settings.js"

[osshelouis]

This is my CalendarController.php, $response has stored the JSON file of my events.
`<?php

namespace ADesigns\CalendarBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

use ADesigns\CalendarBundle\Event\CalendarEvent;

class CalendarController extends Controller
{
/**
* Dispatch a CalendarEvent and return a JSON Response of any events returned.
*
* @param Request $request
* @return Response
*/
public function loadCalendarAction(Request $request)
{
$startDatetime = new \DateTime();
$startDatetime->setTimestamp($request->get('start'));

    $endDatetime = new \DateTime();
    $endDatetime->setTimestamp($request->get('end'));
    
    $events = $this->container->get('event_dispatcher')->dispatch(CalendarEvent::CONFIGURE, new CalendarEvent($startDatetime, $endDatetime, $request))->getEvents();
    
    $response = new \Symfony\Component\HttpFoundation\Response();
    $response->headers->set('Content-Type', 'application/json');
    
    
    $return_events = array();
   
    foreach($events as $event) {
        $return_events[] = $event->toArray();    
    }
   
    
    $response->setContent(json_encode($return_events));
    
    
    return $response;
}

}
Im dont know how you retrieve the JSON encode file on the js file$(function () {
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();

$('#calendar-holder').fullCalendar({
    header: {
        left: 'prev, next',
        center: 'title',
        right: 'month,'
    },
    lazyFetching: true,
    timeFormat: {
        // for agendaWeek and agendaDay
        agenda: 'h:mmt',    // 5:00 - 6:30

        // for all other views
        '': 'h:mmt'         // 7p
    },
    eventSources: [
        {
            url: Routing.generate('fullcalendar_loader'),
            type: 'GET'
             data: {
            filter: 'my_custom_filter_param'
        },
        error: function() {
           //alert('There was an error while fetching Google Calendar!');
        }
        }
    ]
    
    
    
});

});`

Any help would be appreciated, Thanks
