Finally found a satisfying way to deal with interfaces that deliver information, but only upon virtual call.
The solution involves a static variable but any other (and uglier/hackier) solution will do so too.
I applied the method the the JoyStickQuantityListener so that the KeyBinder is now independent on the InputManager.
