//In controller pass the value which you want to use in builder form in array like

$object = new Question();
$form->create(new QuestionType() , $object , array('sqtname'=>2,'question_type'=>2));


//In Form type class
public function buildForm(FormBuilderInterface $builder , array $options)
    {  
     //for setting data field dynamically 
  if (array_key_exists('question_type', $options) && $options['question_type'] != '') {
    $data = $em->getReference("RecrutOnlineStandardBundle:StdQuestionType",$options['question_type']->getId());
  } else {
    $data = "";
  }


  $builder->add('StdQuestionType', 'entity', array(
        'class' => 'TestStandardBundle:StdQuestionType',
        'property' => 'name',
        'empty_value' => 'Sélectionner un question type',
        'required' => true,
        'data' => $data,
        'query_builder' => function(EntityRepository $er ) use ( $options ) {
            if (isset($options['sqtname']) && $options['sqtname'] != '') {
                return $er->createQueryBuilder('sqt')
                                ->where("sqt.name!= ".$options['sqtname']);
            } else{
               return $er->createQueryBuilder('sqt');
            }
        }
    ));
 }

 public function setDefaultOptions(OptionsResolverInterface $resolver)
     {
       $resolver->setDefaults(array(
         'data_class' => 'Test\QuestionBundle\Entity\Question',
         'required' => false,
         'sqtname' => '',
         'question_type' =>'' 
       ));
     }
