for application wide events, use

PHP Code:
this.application.on({ //handle system-application wide events and calls here!!
            
'eventName1'this.event1Handler,
            
'eventName2'this.event2Handler,
            
'eventName3'this.event3Handler
        
}); 
this.control() is used only for the local controller. If you want the event bubbled up to the application level use this.application.on()
