Backbone.js and Symfony2 form validation

Question

I'm creating a single-page app with backbone.js and symfony2 and I need your opinion on one thing.

For example see this create user action. The request is sent by a backbone model (model.save), and I want to check values on the server side. My question is pretty simple, is it pertinent to use the symfony2 form validation to do this check ?

/**
 *
 * @Route("/user", defaults={"_format"="json"}, name="create_user")
 * @Method({"POST"})
 */
public function createUserAction() {
    $request = $this->get('request');

    if (0 === strpos($request->headers->get('Content-Type'), 'application/json')) {
        $data = json_decode($request->getContent(), true);
        $request->request->replace(is_array($data) ? $data : array());
    }

    $entity  = new User();
    $form = $this->createForm(new UserType(), $entity);
    $form->bind($request);
    ... 
}

If yes, how can I do that? Backbone sends JSON request body whereas bind method of Symfony2 form object only accepts URL encoding. I've already tried to use urlencode function without success.

Yes it is pertinent, you should always do server side validation. My question is where is your content variable coming from? I don't see it being assigned in the above code.
