Yiibooster Display Modal From Ajaxlink Or Ajaxbutton

I need to update a modal window and display it when I click in the "EDITAR" button.

CONTROLLER:


public function actionUpdateAjax($id)

    {

        $contratos = ZfContratos::model()->findByPk($id);


        $this->renderPartial('//ZfContratos/_form_update', array('model'=>$contratos), false, true);

    }

INDEX:


<?php $this->beginWidget(

    'bootstrap.widgets.TbModal',

    array('id' => 'actualizar_contrato')

); ?>

    <div class="modal-header">

        <a class="close" data-dismiss="modal">&times;</a>

        <h4>Actualizar contrato</h4>

    </div>

    <div class="modal-body">


        <?php $this->renderPartial('//ZfContratos/_form_update', array('model'=>$contrato));?>


    </div>

    <div class="modal-footer">


        <?php $this->widget(

            'bootstrap.widgets.TbButton',

            array(

                'label' => 'CANCELAR',

                'url' => '#',

                'htmlOptions' => array('data-dismiss' => 'modal'),

            )

        ); ?>

    </div>

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

AND VIEW _contratos

At this moment I have this:


<?php echo CHtml::link('EDITAR', array('//ZfInmuebles/UpdateAjax', 'id'=>$data->zf_contrato_id), array('class'=>'btn', 'id'=>'vermas')); ?>

But I need that to be an ajaxbutton or ajaxlink, that refresh the div "actualizar_contrato" and display it.

I have try this:


 <?php echo CHtml::ajaxLink('EDITAR',array('//ZfInmuebles/UpdateAjax', 'id'=>$data-> zf_contrato_id), array(

          'type'=>'POST',

          "success"=>'js:function(html){

              $("#actualizar_contrato >.modal-body").html(html);

              $("#actualizar_contrato").modal("show");

                }

          '));?>

Thanks!
