Yii Booster Select2Row Don't Work After Renderpartial

I’m trying to use the yiibooster select2row widget in a view updated via ajax. I have a select2row with the list of name of people retrieved by model.

After selecting one I try to update the other fields in the view by ajax and renderpartial. I do that registeriing a script for the on change event.

It works the 1st time, but after the renderpartial it don’t work anymore … and even the widget is not rendered correctly anymore.

Here is my controller action

public function ActionView() {

    // Model Setting

    if(isset($_POST[idKey]) and $_POST[idKey] > 0) {


    } else {

        $docente=new Docente();


    if (Yii::app()->request->isAjaxRequest) {

        echo CJSON::encode(array(

                'divFormScheda'=>$this->renderPartial('_form',array('docente'=>$docente,), true, false),


        } else {

            $this->render('view', array('docente'=>$docente,));



Here my view

// Script to make the ajax update on change of the select2 widget

Yii::app()->clientScript->registerScript('wric', "

jQuery('#Docente_id').on('change', function(e) {

    var idKey = $('#Docente_id').val();



        'data':$(this).serialize() + '&idKey=' + idKey,



        'success':function(data) {





    return false;




    // Display Scheda


    echo CHtml::openTag('div',array('id'=>'divFormScheda'));

    $this->renderPartial('_form', array('docente'=>$docente,), false, false);    

    echo CHtml::closeTag('div');

And here my _form.php used in renderpartial

$form = $this->beginWidget(



        'id' => 'idFormR',

        'type' => 'horizontal',

        'htmlOptions' => array('class' => 'well'),



// Error

echo $form->errorSummary($docente,"Errori riscontrati:<br /><br />");

// Input Hidden to read the idKey to set the ajax post

echo $form->hiddenField($docente, 'id', array('id' => 'idKey'));

// select2row widget for the selection

echo $form->select2Row($docente, 'id',


        'data' => CHtml::listData(Docente::model()->findAll(), 'id', 'cognome'),

        'options' => array(

            'placeholder' => 'Select ...',

            'allowClear' => true,

            'width' => '40%',




// Fields

echo $form->textFieldRow($docente, 'nome', array('class' => 'input-xlarge', 'disabled' => true));


In the form I used an hidden field to store the id used in the script to send the ajax request via POST.

Really I don’t understand why it works only the first time …
