Eselect2 How To Load Selected Data?

Hello,

I have this in my _form:


$this->widget('ext.select2.ESelect2',array(

       'model'=>$model,

       'attribute' => 'authors[]',

       'data'=>CHtml::listData(

           Authors::model()->findAll(), 'AuthorId', 'AuthorName'),

       'options'  => array(

           'placeholder'=>'Select authors',

       ),

       'htmlOptions'=>array(

           'multiple'=>'multiple',

       ),

));

I use it on create method. How can I use it on update method with preload selected data?

Thank you!!
