There is no regular event called 'rightclick'. That's an event
provided by the Maps API. The regular event is called 'click'. So the
'rightclick' event is only definable for map objects according to the
documentation.
Be that as it may, it looks like as if the Maps API makes it
impossible to register any right click on the map and on every DOM
element appended to the map. Seems you can't even use a regular event
listener provided by Javascript for that.
