[ASK] Parsing function result to textfield using AJAX

Hi, I have a dropdownlist and a textfield. If the value of dropdownlist is change, I want to call an action in controller and parsing the result to textfield value. How can I do that?

Here is my code:


echo TbHtml::dropDownList('isr[setting_merit_demerit_id]', $isr['setting_merit_demerit_id'], $this->getMeritList(), 

array('class'=>'span4',  // 'onchange' => 'generateNumber();', 

	'ajax' => array(



		// 'success' =>'js:function(result){$("#tes").val(result).change();}', <--- WHAT SHOULD I PUT HERE?

		'data' => array('setting_merit_demerit_id' => 'js:this.value'),





echo TbHtml::textField('isr[show_in_reportcard]',$isr['show_in_reportcard'], array('class'=>'span1', 'id'=>'tes'));


function actionGetMeritDemeritStatus(){

	$setting_merit_demerit_id = $_POST['setting_merit_demerit_id'];

	$model= SettingMeritDemeritM::model()->findByPk($id);


	return $model->status;


Sorry for my bad english
