Yii Ajax Link Url Behaviour

Below is the code which i used for ajax request

  echo CHtml::ajaxLink(CHtml::image(Yii::app()->baseUrl.'/images/document.png'), Yii::app()->createUrl( 'user/region' ),


                    array( // ajaxOptions


                    'type' => 'POST',


                    'data' => array('blogs_id'=>$model->id),


                    'url'=>Yii::app()->createAbsoluteUrl('companies/blog'),


                    'update'=>'#city_name',


                       


                    ),array('title'=>'Discussion')


                );

But when i click on it, it calls another url like users/region instead of companies/blog.

please help me.

Sorry i solved it
