Magento在模板中调度事件

Question

Desired Logic

I would like my template to dispatch an event every time the user clicks the
on and off buttons. My view.phtml file look likes this...

/*Some Html*/ 


<?php
/*=== Variables ===========*/
$customer = Mage::getModel('customer/session')->getCustomer();
/*$groupId = Mage::getSingleton('customer/session')->getCustomerGroupId();*/
$groupId = $customer->getGroupId();
$group = Mage::getModel('customer/group')->load($groupId);
$groupCode = $group->getCode();

$OnArray = array(
   "value" => "on", 
   "customer" => $customer
    );
$OffArray = array(
   "value" => "off", 
   "customer" => $customer
    );
?>

  /* More HTML * /  

<form action="">
    <input type="radio" name="auto-refill" value="On" onClick = "<?php Mage: dispatchEvent('autoFill_Update', $OnArray ?>" />On<br>
    <input type="radio" name="auto-refill" value="Off" onClick = "<?php Mage: dispatchEvent('autoFill_Update', $OffArray ?>" />Off
</form>

Questions

Did I implement the desired logic correctly ?

Since the php scripts are separated my html code do I lose the
reference to the ON and OFF arrays when I try to pass them in onClick ?

Any guidance is truly appreciated
