dialog can't post

Hi, friends

I have a dialog for update ordering which contain _form_update.php.

why i can’t post[‘oldproduct’] and post[‘newproduct’] from _form_update.php.

view: main.php

function onChangeUpdate_order(changeVal) {

	

	 $('#dialogUpdateOrder').dialog('open');

	 var update_order_id=changeVal.value;

	

   		<?php echo CHtml::ajax(array(

   		

       	'url'=>array('/Order/Update/','id'=>120),

        

   	 	'data'=>"js:{order_id:update_order_id}",	

        'type'=>'post',

        'dataType'=>'json',

        'success'=>"function(data)

        {

            if (data.status == 'failure')

            {

                $('#dialogUpdateOrder div.divFormUpdate').html(data.div);

                      // Here is the trick: on submit-> once again this function!

                $('#dialogUpdateOrder div.divFormUpdate form').submit(onChangeUpdate_order);

            }

            else

            {

                $('#dialogUpdateOrder div.divFormUpdate').html(data.div);

                setTimeout(\"$('#dialogUpdateOrder').dialog('close') \",1000);

            }


        } ",

        ));
