How to run Yii::app()->runController in isAjaxRequest block in Yii?

Question

JavaScript

Good afternoon,

For some reason, this method works in the main body of the action, but nothing is generated with isAjaxRequest (

public function actionCreate()
  {
    if (Yii::app()->request->isAjaxRequest 
    {
                        // Тут не работает  = (((
      Yii::app()->runController('sadmin/hotels/update/id/1416');
      Yii::app()->end();
    }
    else
    {
      $model = new Hotels();

                        // тут работает
      Yii::app()->runController('sadmin/hotels/update/id/1416');

      $this->render('create', ['model'=>$model,]);
    }
  }

ajaxSubmitButton returns empty on success (

echo CHtml::ajaxSubmitButton
            (
                $model->isNewRecord ? 'Добавить номера' : 'Обновить',

                    Yii::app()->createUrl('sadmin/hotels/create'),
                    [
                        'success'=>'js:function(data)
                        {
                            displayMessage(data);
                            $("#hotels-form").remove();
                            $("#crud-hotel").append(data);
                        }',
                        'error'=>'js:function()
                        {
                            alert("Плохо");
                        }',
                    ],
                    [
                        'id'=>'add-hotel',
                        'class'=>'btn btn-primary btn-lg center-block',
                    ]
                );

The button itself works exactly, if you throw some in isAjaxRequestdie($value) , they return

Yii::app()->runController('sadmin/hotels/update/id/1416')

in isAjaxRequest it is definitely processed, because if I deliberately make a mistake inside the line 'sadmin/hotels/update/id/1416' then I get into the error block at ajaxSubmitButton

It is the display of the view that does not work(
