[HELP] Screen Post Construct issue

[Ricoom]

Im trying to modify existing code and for example have taken mainscreen as example. On mainscreen theres function that defines self.play_button. It seems when my mod loads tgat adds class post construct screen yet hasn't executed that function so I can't change its values. Would it be possible to write something on lines. AfterAllLoaded () --do stuff end. So I could go ahead and for example edit the button text or color or etc
