Why isn't this event triggered?

Module.php

class Module 
{
    public function onBootstrap($e)
    {
        $moduleManager = $e->getApplication()->getServiceManager()->get('modulemanager');
        $sharedEvents = $moduleManager->getEventManager()->getSharedManager();
        $sharedEvents->attach('Zend\Mvc\Controller\AbstractRestfulController', MvcEvent::EVENT_DISPATCH, array($this, 'mvcPreDispatch'), -100);
    }

    public function mvcPreDispatch($event) 
    {
        echo "Do this..."; die;
    }
}
