* return $this->backendControllerProxy->runAjaxHandler($handler);
* }

* });
*
* Or
*
* $this->controller->bindEvent('ajax.beforeRunHandler', function ((string) $handler) {
* if (strpos($handler, '::')) {
* list($componentAlias, $handlerName) = explode('::', $handler);
* if ($componentAlias === $this->getBackendWidgetAlias()) {
