you can use like this:

                        //Camelize actions
                        $eventsManager->attach('dispatch:beforeDispatch',function ($event,$dispatcher){
                            $dispatcher->setActionName(Phalcon\Text::camelize($dispatcher->getActionName()));
                        });
