Why I can't change Wildcard buffer text color?

[heyo]

I've created list and create callback to this function :
And here u see marked line which changes text color but it's not working

[heyo]

Nevermind I just create new dropdown elements when i click on button and it changes to default colors. Now working ok. Its my fault
