How to use SetText with List View?

Im new to UE4 but I believe something has changed with this since this solution was posted. I have tried creating a ‘Data Object’ from a primary data asset class and a generic object class, and implemented the User Object List Entry Interface in both, but they wont show up as options in my listview widget for the entry widget class. However I can get a widget class with the implemented interface to show up. Am I missing something or doing something wrong? I dont know if it makes a difference but I am only using blueprints, no C++.
