Text block doesn't get value from function with Game Instance

I wanted in a widget for a Text (and if possible, Editable Text) block to get variable from game instance and show it on screen.
So I created a function that takes variable from Game Instance and converts it into text and binded it into Text in Content of Text Block but it never wants to show any value ingame, text is just blank.
Any clue how to fix this?
