ajax validation in yii

I created a ajax submit button to submit a form.

The form is working Good and all the functionalty which I need working perfectly.

I enabled Ajax validation and a success message also. The problem occurs when I partial redirect the form.

The ajax function and validation is not working.

Controller


public function actionCreate()

{

    $model=new Comments;


    // Uncomment the following line if AJAX validation is needed

    $this->performAjaxValidation($model);


    if(isset($_POST['Comments']))

    {

        $model->attributes=$_POST['Comments'];

        // echo '<pre>';print_r($model->attributes);die();

        $valid = $model->validate();


        if($valid){

            if($model->save()){

            echo CJSON::encode(array('status'=>'success'

                ));

        }

        }else{

            $error =CActiveForm::validate($model);

            if($error != '[]')

                echo $error;

            Yii::app()->end();

        }

    }

}

View/_form


<?php 

$form = $this->beginWidget('CActiveForm',array('id'=>'comments-form',

    'enableAjaxValidation'=>true,

    'action'=>$this->createUrl('Comments/create'),

    'enableClientValidation'=>true

    ));
