Symfony 2 + Bootstrap - php

Question

How can I adapt my form to implement bootstrap ?
My function for create form is:
private function createCreateForm(User $entity)
{
$form = $this->createFormBuilder($entity, array(
'action' => $this->generateUrl('user_create'),
'method' => 'POST',
))
->add('username')
->add('email')
->add('password', 'repeated', array(
'first_name' => 'password',
'second_name' => 'confirm',
'type' => 'password',
))
->add('submit', 'submit', array('label' => 'Create'))
->getForm();
return $form;
}
My views is
{{ form_start(form) }}
{{ form_row(form.username, { 'attr': {'class': 'form-control', 'placeholder': 'Imię oraz nazwisko'} }) }}
{{ form_row(form.password, { 'attr': {'class': 'form-control', 'placeholder': 'Password'} }) }}
It is working for username but not for the password, some sugestion ? How can i create our own form ?
My bootstrap:
<form action="#" class="form-horizontal">
<div class="form-body">
<div class="form-group">
<label class="col-md-3 control-label">NAME</label>
<div class="col-md-4">
<input type="text" class="form-control" placeholder="NAME
</div>
</div>
<div class="form-actions fluid">
<div class="col-md-offset-3 col-md-9">
<button type="submit" class="btn blue">Add</button>
<button type="button" class="btn default">Anuluj</button>
</div>
</div>
</form>

Use Mopa Bootstrapbundle https://github.com/phiamo/MopaBootstrapBundle
In your controller:
$this->createForm(
MyFormType(),
$entity,
array('attr' => array('class' => 'form-horizontal'))
);
