[fw-mvc] Dojo forms and custom view scripts

hi
if use zend form dojo whitout custom view script works all but if set
the form don't submit (use SubmitButton element) and if use a normal
submit button return the $_POST array whitout the form fields that using
zend dojo elements...why??

This is the element decorator:
> public $elementDecorators = array(
> 'ViewHelper',
> array(array('data' => 'HtmlTag'), array('tag' => 'td', 'class' => 'element')),
> array('Label', array('tag' => 'td')
>
> ));
