Listeners doesn't trigger on DialogFragment

[Cristian Achille]

Hello, i'm getting this weird error that i don't know how to debug, 

I have an activity that calls a DialogFragment which does a POST request to my rest api,  but when i'm executing the request i don't get nothing from both onRequestFailure and onRequestSuccess.

I'll include just the DialogFragment class because i'm pretty sure that there is where the bug is.

Note: I do have spiceManager active on the activity that calls the DialogFragment, and it is stopped on onStop() method.
