DropDownList doesn't respond to onchange event


I’m new to Yii, JavaScript and almost new to PHP.

I have a dropdownlist and I would like it to do something when the user selects an item. I attach an action to onchange event. In the example below, it should create an alert box. But nothing happens when the user makes a selection. clientvalidation is enabled and I don’t know if that has anything to do with the problem. Any help would be great. Thanks.


<?php $form = $this->beginWidget('CActiveForm', array(

		 'id' => 'register-form',

		 'enableClientValidation' => true,

		 'clientOptions' => array(

			  'validateOnChange' => true,

			  'validateOnSubmit' => true,




<?php echo $form->dropDownList($model, 'provider', array('2'=>'Yes', '0'=>'No'), 

				  array('empty'=>'Choose one') 


				  ); ?>

Hello, and welcome.

Have you tried with

<?php echo $form->dropDownList($model, 'provider', array('2'=>'Yes', '0'=>'No'), 


                                          'empty'=>'Choose one', 



                                  ); ?>

That works! Thank you so much.
