Problem in user view group when updating ListViews

Question

firstly, I created a repo on gitHub with a sample project with my error in it: https://github.com/renaudfavier/SampleBug

I am having difficulty with my lists in my customViewGroups: I will simulate an assynk data request, then I tring to populate my list, and there are difficulties with it. Please note that there is a little bust in this application, because I need it in my big one. I cannot go to fragments.

My problem is that my listView does not update, it happens when I open my menu
