Yii2 依赖自动完成发送额外参数

Question

下面是两个 Yii2.0 Autocomplete 小部件的 sn-ps

 <?php 
        echo $form->field($model, 'countryId')->begin();
        echo Html::activeLabel($model, 'countryId', ["class"=>"control-label col-md-4"]); ?>
       <div class="col-md-5">
         <?php 
                $data = Country::find()->select('countryName as label, id as id')->asArray()->all();
                echo AutoComplete::widget([
                        'name' => 'countryId',
                        'clientOptions' => [
                                'source' => $data,
                                'autoFill'=>true,
                                'minLength'=>'1',
                                'select'=>"js:function(event,item){\$(\"#countryid\").val(item[1]);})",

                             ],
                         'options' => [
                                'class' => 'form-control',
                             ],
                        ]);
            ?>
         <?php echo Html::activeHiddenInput($model, 'countryId'); ?>
         <?php echo Html::error($model, 'countryId', ['class'=>'help-block']); ?>
         </div>
 <?php echo $form->field($model, 'countryId')->end();?>

对于状态：

    <?php 
        echo $form->field($model, 'stateId')->begin();
        echo Html::activeLabel($model, 'stateId', ["class"=>"control-label col-md-4"]); ?>
       <div class="col-md-5">
         <?php 
                echo AutoComplete::widget([
                        'name' => 'countryId',
                        'clientOptions' => [
                                'source' => 'js:function(request, response) {
                                                \$.getJSON(\"'+Yii::$app->urlManager->createUrl("site/get-states")+'\", { country: \$(\"#countryid\").val() }, 
                                                response);
                                            }',
                                'autoFill'=>true,
                                'minLength'=>'1',
                                'select'=>"js:function(event,item){\$(\"#stateid\").val(item[1]);}",

                             ],
                         'options' => [
                                'class' => 'form-control',
                             ],
                        ]);
         echo Html::activeHiddenInput($model, 'stateId');
         echo Html::error($model, 'stateId', ['class'=>'help-block']); ?>
         </div>
 <?php echo $form->field($model, 'stateId')->end();?>

我的 getStates 控制器是：

public function actionGetStates(){
    if(Yii::$app->request->isAjax && isset($_GET['term']) && isset($_GET['country'])) {
        /* term is the default GET variable name that is used by
         / the autocomplete widget to pass in user input
         */
       // \Yii::$app->response->format = 
        $name = $_GET['term'];
        $country = $_GET['country'];

        // this was set with the "max" attribute of the CAutoComplete widget
        $limit = min($_GET['limit'], 50);

        $statesArray = State::find()->select('stateName as label, id as id')->where('stateName LIKE :sterm AND countryId=:countryId')->params([':sterm'=>"%$name%", ':countryId'=> $country])->all();


        return $statesArray;
    }
}

这给我一个错误：

TypeError: this.source 不是函数

this.source( { term: value }, this._response() );

请帮我将国家 ID 发送给我的控制器。我也尝试过 extraParams 选项，但 jquery ui 不再支持该选项。
