How to use a EditableColumn

Hello, a have this code:




<?php $form= $this->beginWidget('booster.widgets.TbActiveForm',array('id' => 'verticalForm',)); ?>            

    <div class="campo">

        <?php 

                $this->widget('booster.widgets.TbGridView', array(

                    'id' => 'dispositivo-grid-list',

                    'dataProvider' => $empresa->search(),

                    'filter' => $empresa,

                    'columns' => array(                                                 

                        array(

                            'class' => 'booster.widgets.TbEditableColumn',

                            'name' => 'dni_per',

                            'htmlOptions'=>array('width'=>'150'),

                            'editable' => array(

                                'type' => 'number',

                                'placement' => 'right',

                                'inputclass' => 'span3',                               

                                'url'=> Yii::app()->createUrl('empresa/editable'), 

                            ),                            

                        ),              

                    ),                    

                ));                

            ?> 

    </div>    

        <?php $this->endWidget(); ?>



and in my Controller is:




public function actionEditable()

    {        

        die("enter");

        Yii::import('booster.widgets.TbEditableColumn');

        $es = new TbEditableColumn('number');

        $es->update();

    }



but never enter into the active function…

Can you help me please?

Thanks!!
