On Localize Callback doesnt work

Are you just trying to fill a popup whenever the language changes?
Or trying to localize each of the sub strings of the popup?
Or just want to execute a function when the language changes?

Let's imagine I have a very generic popup with some info text. In that context, the term selected itself its completely irrelevant.

That specific popup can be used in many scenarios inside the game. Inside the callback I'll be using a global variable to flag which scenario to work with..
