RXJAVA2 disposable exiting without any callback

[Android Central Question]

am trying to provide pagination to one of my android application using MVP architecture, am using RXJAVA2 composite disposable in combination with concatmap to get remote results, am exposing the instance of presenter in Activity. But my disposable is returning object without invoking any callback. Can some one please provide solution for the same. If you have come across same situation.
