One simple solution is for your binding to pass the event type into your
callback. For example:

            lambda event, virtual="<<CustomOne>>": self.on_virtual(virtual,
            lambda event, virtual="<<CustomTwo>>": self.on_virtual(virtual,
    def on_virtual(self, virtual, event):
        if (virtual == "<<CustomOne>>"):
