Why my code doesn't work? Controller: ```php use Phalcon\Tag;

class TicketsController extends ControllerBase { public function initialize() { $this->view->setTemplateBefore('public'); Tag::setTitle('Билеты'); }

public function indexAction()
{

}

public function eventIdAction()
{
    Tag::appendTitle(' на событие');

}

} ``` in action view I want get current title: ```php <?php var_dump(Phalcon\Tag::getTitle()); ?> ``` and get this: string(28) " " string is empty but size 28 characters
