已调用Magento表单块，但无法在phtml中访问函数

我有一个街区

app/code/local/Company/Club/Block/Adminhtml/Edit/Form.php
class Company_Club_Block_Adminhtml_Edit_Form extends Mage_Adminhtml_Block_Widget_Form {

    public function getSubmitUrl()
    {
        die; //this is never reached
        return $this->getUrl('company_club/Customer/Save');
    }
}

我在控制器中调用它：

public function AddAction()
{
    $this->loadLayout();
    $this->_addContent($this->getLayout()->createBlock('company_club/adminhtml_edit_form'));
    $this->renderLayout();
}

它指的是一个布局

<company_club_customer_add>
    <update handle="main_club_update"/>
    <reference name="root">
        <block type="company_club/adminhtml_edit_form" name="addClubCustomer"/>
        <action method="setTemplate">
            <template>Club/Customer/Add.phtml</template>
        </action>
    </reference>
</company_club_customer_add>

俱乐部/客户/Add.phtml

phtml显示良好并调用

<form action="<?php echo $this->getSubmitUrl(); ?>" method="POST" name="formCustomer" id="formCustomer">

---

我做了一个丑陋的修复，但我无法检测到控制器的修改：

$form = new Company_Club_Block_Adminhtml_Edit_Form();
<?php echo $form->getSubmitUrl(); ?>

$form=new Company\u Club\u Block\u Adminhtml\u Edit\u form（）；
