无法在yii1中更改cjuidatepicker中用户视图的日期格式

Question

$this->widget('zii.widgets.jui.CJuiDatePicker',array(
                            'name'=>'date_from',
                            'id' => 'date_from',
                            //'value'=> date('d/m/Y',strtotime($date_from)),
                            'options'=>array(
                            'dateFormat' =>'dd/mm/yy',
                            'altFormat' =>'dd/mm/yy',
                            'changeMonth' => true,
                            'changeYear' => true,                                
                            'showAnim'=>'slide',
                            'showButtonPanel'=>true,
                        ),
                        'language' => 'en-GB',
                        'htmlOptions'=>array(
                            'class'=>'form-control'
                        ),
                    ));

This is the code for the date picker so I want the user to view the date in the following format: dd/mm/yy. I want it seperated with slashes.
