Sending ajax form, several time

There is my code in following: (Yii framework)

View form: view.php

<div class="form">
<?php
    $form = $this->beginWidget('CActiveForm',array(
        'id'=>'user-profile',
        'action' => 'index.php?r=upanel/user/update',
        'method' => 'post',
    ));
?>
    <?php $form->errorSummary($model) ?>
     . . .
     . . .
     . . .
     . . .
     . . .
    <div class="row buttons">
        <?php
            $url = Yii::app()->createUrl('upanel/user/update');
            echo CHtml::ajaxSubmitButton('Update Profile',$url,array(
                'type'=>'POST',
                'data'=> "js:$('#user-profile').serialize()",//var data = $('#user-form').serialize();
                'datatype'=>'html',
                'success'=>'callback',
                'error'=>'error',
            ));
        ?>
    </div>

<?php $this->endWidget() ?>
</div> <!-- End CActiveForm-->

<p><?php echo Yii::app()->user->getFlash('success') ?></p>

<script>
function callback(data,status){
    if (status=='success')
            $('#user-profile').html(data);
}

function error(jqXHR, textStatus , errorThrown){
    console.log(jqXHR);
    $('#error').html('callback error');
}
</script>

actionUpdate in controller: actionUpdate()

public function actionUpdate()
{
    $model=$this->loadModel(Yii::app()->user->id);
    $model->scenario = 'updateProfile';

    if(isset($_POST['User'])){
        $model->attributes=$_POST['User'];
        if($model->validate()){
            if ($model->save()){
                    Yii::app()->user->setFlash('success','Successfully Updated');
                    $this->renderPartial('view',array('model'=>$model));
            }
        }
    }
}

Problem is: when the form is sent first time, print_r($_REQUEST)show the data form been sent(in post method), but after that view.php rendered with partialrender() in actionUpdate, print_r($_REQUEST) show there is no data in the sent form to the server despite the form is filled. ?

Solved. Just only a clumsy mistake.

In callback function on success i should have updated div HTML element instead form.

Changing from:

function callback(data,status){
    if (status=='success'){
            $('#user-profile').html(data);
    }

To:

function callback(data,status){
    if (status=='success'){
            $('#user-profile-div').html(data);
    }

Thanks friends for guidance.

Please Take care these points when handling ajax button,link in Yii.

1.when using CHtml::ajaxSubmitButton or CHtml::AjaxLink use 'live'=>false and should have an unique id:

array('id'=>'uniqueId', 'live'=>false)

2.If it is an AJAX request, Use

$this->renderPartial('_view', array(
                   'model'=>  $model,
               ), false, true);

3.if it is a normal request Use

$this->renderPartial('_view', array(
                   'model'=>  $model,
           ), false, false);

4.Assign to your ajax link or button a random ID

CHtml::ajaxLink('send a message', '/message', 
    array('replace' => '#message-div'), 
    array('id' => 'send-link-'.uniqid())
);

Use this to stop the form being regenerated and updation on previos state:

$this->renderPartial('view',array('model'=>$model),false,true);

Note the false,true added in renderPartial method.
