How to make a composite Zend Form Element that includes a Dojo Field

Question

I used the zendcast video to get me this far. The form is properly displayed. However, I need to change the display order box into a number box of zend dojo type. I cannot figure it out. Even help with examples would be great.

<?php
class My_View_Helper_CategoryDetailElement
 extends Zend_View_Helper_FormElement
 {
 protected $html = '';
 public function CategoryDetailElement($name, $value = null, $attribs = null)
{
    $type = $description = $displayOrder = $time = '';

    if($value)
    {    
     $type = $value->type;
     $description =  $value->description;
     $displayOrder = $value->displayOrder;
     $time = $value->time;
    }

    $helper = new Zend_View_Helper_FormText();
    $helper->setView($this->view);

    $helper_label = new Zend_View_Helper_FormLabel();
    $helper_label->setView($this->view);

    $helper_select = new Zend_View_Helper_FormSelect();
    $helper_select->setView($this->view);

    $helper_textarea = new Zend_View_Helper_FormTextarea();
    $helper_textarea->setView($this->view);

    $this->html .= $helper_label->formLabel($name . '[type]', 'Type: ', array());
    $this->html .= $helper_select->formSelect($name . '[type]', $type, array(), array('individual'=>'individual', 'team'=>'team'));
    $this->html .= "<br />";
    $this->html .= $helper_label->formLabel($name . '[description]', 'Description: ', array());
    $this->html .= $helper_textarea->formTextarea($name . '[description]', $description, array());
    $this->html .= "<br />";
    $this->html .= $helper_label->formLabel($name . '[displayOrder]', 'Display Order: ', array());
    $this->html .= $helper->formText($name . '[displayOrder]', $displayOrder, array());
    $this->html .= "<br />";
    $this->html .= $helper_label->formLabel($name . '[time]', 'Time: ', array());
    $this->html .= $helper->formText($name . '[time]', $time, array());

    return $this->html;
}

}

?>
