afterAction and returning method in yii2?

i have controller in common folder that have method test

  public function actionTest() {
    $s = "sdfs";
    return $s;
}

And have afterAction for this action like:

   public function afterAction($action) {
    if ($action->id == "test") { 
       echo 'here afterActioin';
     }
   }

and i call the test action from another controller :

public function actionTest3() {
  echo Yii::$app->runAction('travia/test');
 }

the problem is when i call the test3 in browser nothing display but if i comment the afterAction the method will return . where is the problem what's the behaviour of the afterAction that doen't let my action to return something?

Yii2 docs

This method is invoked right after an action is executed. The method will trigger the EVENT_AFTER_ACTION event. The return value of the method will be used as the action return value. If you override this method, your code should look like the following:

public function afterAction($action, $result)
{
    $result = parent::afterAction($action, $result);
    // your custom code here
    return $result;
}
