Formatting entity in json format does'nt show in view - json

Question

This is the view, the success function should make changes in the <p id="mondiv"></p>tags.
<input type="button" value="Refuser" class="refuser" id="{{ demande.id }}">
<p id="mondiv"></p>
<script>
$(".refuser").click(function () {
$.ajax({
url: '{{ path('verifier_demandes') }}',
type: 'POST',
data: {'id_demande': this.id},
dataType: 'json',
success: function (data) {
$.each(data,function (i,e) {
$('#mondiv').append('<ul>'
+'<li>'+e.id+'</li>'
+'<li>'+e.etat+'</li>'
+'<li>'+e.user.nom+'</li>'
+'<li>'+e.user.prenom+'</li>'
+'<li>'+e.user.username+'</li>'
+'</ul>');
})
},
error: function(data) {
alert('error');
}
})
}
);
This is the controller, the entity gets deleted like intended but since then i can't change my view element ( the success function )
if($request->isXmlHttpRequest())
{
if ($request->get('id_demande')) {
$id_gerant = $request->get('id_demande');
$gerant = new Gerant();
$gerant = $em->getRepository("GestionBoutiquesBundle:Gerant")->findOneBy(array('id' => $id_gerant));
$em->remove($gerant);
$em->flush();
$demandes = new Gerant();
$demandes=$em->getRepository('GestionBoutiquesBundle:Gerant')->findBy(array('etat'=>false));
$ser= new Serializer(array(new ObjectNormalizer()));
$data=$ser->normalize($demandes);
return new JsonResponse($data);
}
}
I have looked from both sides, the controller sending back the Json response, and from the view, but couldn't find any result.
EDIT: knowing that the $demandes i'm trying to send back with Json is an array of users, each user has an id, etat, nom, prenom, username..

You made a POST request so you should be able to access to the post data as follow:
$id_gerant = $request->request->get('id_demande');
if($id_gerant) {
....
instead of:
if ($request->get('id_demande')) {
$id_gerant = $request->get('id_demande');
....
As described here in the doc Symfony Request Object
Hope this help
