How to access form elements in controller symfony2 - symfony

Question

I've generated the form through entity generator,
I've extended the Cobrand Controller
class CobrandController extends Controller
{
public function createAction()
{
// the key used to lookup the template
$templateKey = 'edit';
if (false === $this->admin->isGranted('CREATE')) {
throw new AccessDeniedException();
}
$object = $this->admin->getNewInstance();
$this->admin->setSubject($object);
/** #var $form \Symfony\Component\Form\Form */
$form = $this->admin->getForm();
$form->setData($object);
if ($this->getRestMethod()== 'POST') {
// $cobrand = new Cobrand();
$em=$this->getDoctrine()->getManager();
$cobrand=new Cobrand($em);
$form->bind($this->get('request'));
$isFormValid = $form->isValid();
// persist if the form was valid and if in preview mode the preview was approved
if ($isFormValid && (!$this->isInPreviewMode() || $this->isPreviewApproved())) {
$this->admin->create($object);
if ($this->isXmlHttpRequest()) {
return $this->renderJson(array(
'result' => 'ok',
'objectId' => $this->admin->getNormalizedIdentifier($object)
));
}
$this->addFlash('sonata_flash_success','flash_create_success');
// redirect to edit mode
return $this->redirectTo($object);
}
// show an error message if the form failed validation
if (!$isFormValid) {
if (!$this->isXmlHttpRequest()) {
$this->addFlash('sonata_flash_error', 'flash_create_error');
}
} elseif ($this->isPreviewRequested()) {
// pick the preview template if the form was valid and preview was requested
$templateKey = 'preview';
$this->admin->getShow();
}
}
$view = $form->createView();
// set the theme for the current Admin Form
$this->get('twig')->getExtension('form')->renderer->setTheme($view, $this->admin->getFormTheme());
return $this->render($this->admin->getTemplate($templateKey), array(
'action' => 'create',
'form' => $view,
'object' => $object,
));
}
}
Here's my entity code,
class Cobrand
{
/**
* #var \DateTime
*/
private $created;
/**
* #var \DateTime
*/
private $updated;
/**
* #var string
*/
private $name;
/**
* #var string
*/
private $code;
/**
* #var string
*/
private $logo;
/**
* #var boolean
*/
private $cobrandedProductsOnly;
/**
* #var integer
*/
private $id;
/**
* #var \Doctrine\Common\Collections\Collection
*/
private $productPrices;
/**
* #var \Doctrine\Common\Collections\Collection
*/
private $promocodes;
/**
* Constructor
*/
public function __construct()
{
$this->productPrices = new \Doctrine\Common\Collections\ArrayCollection();
$this->promocodes = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* Set created
*
* #param \DateTime $created
* #return Cobrand
*/
public function setCreated($created)
{
$this->created = $created;
return $this;
}
/**
* Get created
*
* #return \DateTime
*/
public function getCreated()
{
return $this->created;
}
/**
* Set updated
*
* #param \DateTime $updated
* #return Cobrand
*/
public function setUpdated($updated)
{
$this->updated = $updated;
return $this;
}
/**
* Get updated
*
* #return \DateTime
*/
public function getUpdated()
{
return $this->updated;
}
/**
* Set name
*
* #param string $name
* #return Cobrand
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
/**
* Set code
*
* #param string $code
* #return Cobrand
*/
public function setCode($code)
{
$this->code = $code;
return $this;
}
/**
* Get code
*
* #return string
*/
public function getCode()
{
return $this->code;
}
}
User will enter the values on the form and I wan't to access those values in the createAction method of controller.
I want to change the value of $name in the controller.
How to access this ?
Thanks,

Try this after binding request
$form->get('name')->setData('new value');
