For some reason this doesnt work and I can't find a way to make it work!

on my controller named ExplicacaoController I have this:

public function accessRules()

...

'actions'=>array('index','view', 'test', 'ajaxrequest'),

...

public function actionAjaxRequest()

    {

      $val1 = $_POST['val1'];

      $val2 = $_POST['val2'];

      echo something;



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

    }

On my view I have:

<script type=text/javascript>

...

$.ajax({

      type: POST,

      url:    <? echo Yii::app()->createUrl('explicacaoController/ajaxRequest'); ?>,

      data:  {val1:1,val2:2},

      success: function(msg){

           alert(Sucess)

          },

      error: function(xhr){

      alert(failure+xhr.readyState+this.url)



      }

    });

...

What happens is that I allways get this error:

failure4<? echo Yii::app()->createUrl('explicacaoController/ajaxRequest'); ?>

I really need some help with this
