db table id set to 0 after db save

Question

i have a sequence of code steps

before HTML Render
custom code:

<?php
$form->data['reg_id'] = JRequest::getInt('reg_id','','get');
?>

then HTML Render

On Submit
db save with update conditions

<?php 
return array("reg_id"=>$form->data['reg_id']);
?>

redirect with params

chronoform="MORA-Menu"
reg_id=reg_id

but the value of $form->data['reg_id'] =0 after the db save. why?
