Form not valid in Symfony2 - symfony

Question

I am trying to process a form in Symfony2, I get all the values from it in the controller, but when I call:
$form->isValid()
it returns false. I am trying to process the form in a different Controller.
The form is rendered in two pieces, first some personal data and then some more information, but in the submit event of the form, I join all values serializing the forms. This is how I render the form in the view:
<form id="myform" action="{{ path('_process_my_form') }}" {{ form_enctype(form) }} method="POST">
{{ form_errors(form) }}
{{ form_widget(form._token) }}
{{ form_widget(form.first_name, {'attr': {'class': 'form-control'}} ) }}
... // then I render the rest of the personal information widgets
<button type="submit" class="btn btn-info btn-block">Submit</button>
</form>
<form id="myform2">
{{ form_widget(form.job_name, {'attr': {'class': 'form-control'}} ) }}
... // then I render the rest of the widgets (not personal information)
</form>
Then, in the Ajax request, I join the two forms like this:
$("#my_form").submit(function(e) {
e.preventDefault();
$.ajax({
type: e.target.method,
url: e.target.action,
data: $("#my_form").serialize() + $("#my_form2").serialize(),
beforeSend: function( xhr ) {},
success: function(data) {
//do something...
}
});
});
My _process_my_form rule looks like this:
_process_my_form:
pattern: /ajax/process-my-form
defaults: { _controller: MyBundle:User:processMyForm }
This is the Controller who controls the Ajax request:
public function processMyFormAction(Request $request)
{
if ($request->isMethod('POST'))
{
$myEntity = new myEntity();
$form = $this->container->get('form.factory')->create(new myFormType(), $myEntity);
$form->bind($request);
if ($form->isValid())
{
//Process the form... this code is never excecuted :(
}
}
}
Am I doing something wrong???
Thanks!!!

As of Symfony 2.3 I believe they changed the form handle from
$form->bind($request);
to
$form->handleRequest($request);
However I'm not sure if the former is still supported? As far as I can see, the bind method not longer exists in the Form Interface
