To answer your original question,

Replace:

$form = $this->createForm

With:

$form = $this->container->get('form.factory')->create($type, $data, $options);

The createForm method is just a convenience method defined in Symfony\Bundle\FrameworkBundle\Controller\Controller. For various reasons, 3rd party libraries tend not to extend the Controller class. Hence createForm is not available.

The real question is: why are you trying to extend the Profile controller? In most cases it is not necessary. It's better to do your customization by listening to events. That of course assumes you are using the development version of FOSUserBundle.
