The rationale for the event handler name was to follow patterns like global event handlers present in the DOM where [these are always lower case][1]. Maybe it's not a good idea. Also note that these handlers are not the same as the one we put in objects like `_onSomething` as they are just methods part of the object called when a event is listened to, not a way to attach an external handler.
