How to use the qi.bind function in qi

    @qi.bind()
    def disconnectSubscribers(self):
        """ disconnect all subscribers from callbacks """
        qi.info(self.serviceName, "DISCONNECTING SUBSCRIBERS")
        if self.subscribeToggle:
            for event in self.subscribers.keys():
                future = qi.async(self.disconnectSubscriber, event, delay = 0)
                future.wait(1000) # add a timeout to avoid deadlock
                if not future.isFinished():
                    qi.error(self.serviceName, "disconnectSubscribers", "Failed disconnecting %s subscribers" % event)
            self.subscribeToggle = False

    @qi.bind(qi.Dynamic, qi.AnyArguments)
    def special(self, *args):
        print("args:", args)

    @qi.bind()
    def connectSubscribers(self):
        """ generate & connect all subscribers to callbacks """
        if not self.subscribeToggle:
            for event in self.subscribers.keys():
                self.subscribers[event]["subscriber"] = self.memory.subscriber(event)
                self.subscribers[event]["uid"]        = self.subscribers[event]["subscriber"].signal.connect(self.subscribers[event]["callback"])
            self.subscribeToggle = True
