If you see in example in given link the code changed for you will be
<?php
echo
$this->Js->get('#parentdropdownid')->event->('change',$this->JS->request(array(
'controller'=>'controllername', //where request will be processed
'action'=>'actionname'),
array(
'update'=>'#idofchildcategory',
'async'=>true,
'dataExpression'=>true,
'method'=>Post,
'data'=>$(this).serialize()'),
false))
?>
You can look up for jQuery Ajax request help in case you are unable to
understand any parameters..
