Which exceptions are being caught with beforeException?

So in my actions some functions may throw an exception, so I wanted to handle those in a single place. I thought a beforeException event was exactly what I was looking for. However I could not get it working.

Basically that's what I was doing

$eventsManager = new Phalcon\Events\Manager();
$eventsManager->attach("dispatch", function($event, $dispatcher, $exception) {
    die(var_dump("Got there"));
});
$this->getDI()->get("dispatcher")->setEventsManager($eventsManager);

and then in action for example

public function indexAction() {
    throw new \Exception("test");
}

However it didn't work. Exceptions thrown in actions were not caught. So, maybe they have to be specific exceptions?
