So how do we have call backs from our publisher or subscriber?

You can have one callback per subscription, I don't know why you'd have a callback for a publisher. We might have callbacks for events like when a subscription is matched on a publisher or something like that, but in typical use cases you'd never have a callback on a publisher...

Has multiple call backs been enabled?

No, but as I said above, you can have your own list of callbacks which you call in your subscriptions single callback.
