How in yii in CJuiAutoComplete, in addition to the value field, to pick up other form parameters?

Question

Yii

I looked in the documentation www.yiiframework.com/doc/api/1.1/CJuiAutoComplete ,
How to pick up some other form elements in addition to the value of the input field, for example:
some

beforeWrite =>

addOtherTerms()
{
      'stars'=> $('#stars').val(),
      'country'=>$('#country').val(),
}

Fragment from the view:

                        'name'=>'place_id',
