can you please give me more details?
What the exact problem? Can you point me to the line number in your sample?

Yes between lines 61 to 77 were my attempts to create the callback but with no success sadly.
My goal is just to discover the public rooms on our jabber server.

here you can see an example how the callack work in general. Its this sample its for vcards:

Why are you not using the new async/await functionality? This is much easier to use, makes code simpler and easier to maintain.
