oneupuploader with jQuery-File-Upload UI - php

Question

I'm trying to setup jQuery-File-Upload UI with oneupuploaderBundle on a symfony2 Website.
After a lot of tears, the upload process works as I want,but I can't make the Json response work avec the upload.
I use the PostUploadEvent of the oneupuploaderBundle, And tied a lot of solution to send a corecte jSon response to jQuery-File-Upload UI, but i still have an error message when the file has been uploaded.
In the doc, the ask to send a resonse like this:
{"files": [
{
"name": "picture1.jpg",
"size": 902604,
"url": "http:\/\/example.org\/files\/picture1.jpg",
"thumbnail_url": "http:\/\/example.org\/files\/thumbnail\/picture1.jpg",
"delete_url": "http:\/\/example.org\/files\/picture1.jpg",
"delete_type": "DELETE"
}
]}
Here is mine :
{"files": [
{
"url": "\/ishowpro-cms\/web\/app_dev.php\/library\/file\/image\/originals\/51dbd9a13a065-screen-shot-mini.png",
"thumbnail_url": "\/ishowpro-cms\/web\/app_dev.php\/library\/file\/image\/thumbnails\/51dbd9a13a065-screen-shot-mini.png",
"name": "screen-shot-mini.png",
"type": "image/png",
"size": 1192,
"delete_url": "http://nourltodelete.com",
delete_type: "DELETE"
}
] }
The URls are OK.
I tried to return the response with
return new JsonResponse($jsonResponse);
with the Normal response object and json headers, I tried to create an entity and serialize it :
$responseObjectFile = new JqUploaderFile();
$responseObjectFile->setName();
$responseObjectFile->setSize();
$responseObjectFile->setUrl();
$responseObjectFile->setThumbnail_url();
$responseObjectFile->setDelete_url($this->router->generate('show_image_link', array('slug'=>$file->getSlug(), 'extension'=>$file->getExtension(), 'size'=>'originals'), true));
$responseObjectFile->setDelete_type("DELETE");
//create serializer to encode Entity
$encoders = array(new XmlEncoder(), new JsonEncoder());
$normalizers = array(new GetSetMethodNormalizer());
$serializer = new Serializer($normalizers, $encoders);
$jsonContent = $serializer->serialize($responseObjectFile, 'json');
//add entity in array and unserilize it....
$responseCode = array('files'=>array($jsonContent) );
And also to use the $event->getRequest(); of the object.
But nothing works.
Is their someone who can help me please ?
Thank you in advance.

Thanks to devsheeep, here is the solution.
Really simple when you know it :
$response = $event->getResponse();
$files = array();
$files[0] = array(
'name' => $file->getFileName(),
'size' => $file->getSize(),
'url' => "Your URL",
'thumbnail_url' => "Your thumb URL",
'delete_url' =>"Your delete URL",
'delete_type' => 'DELETE'
);
$response['files'] = $files;
And we are in an Event context, return values have no effects. Instead we are working with references. So just omit the return statement.
5 to create it, I love.
Thanks again to desheep and the 1up.io team, they are great professionals of the Symfony Framework.
