Change a RadButton theme after application theme has been applied

[JDLC]

I've applied a theme to the application using  

ThemeResolutionService.ApplicationThemeName = "MyTheme";

All works as expected, my theme is applied.

Later on in the application, one specific RadButton needs to have a different theme applied programatically, say "MyThemeWarning"

So I try

myButton.ThemeName = "MyThemeWarning";

but nothing changes, the button remains with the theme that was applied to the application. I have verified MyThemeWarning is being loaded by the ThemeResolutionService. 

What is the correct way to change the theme of a specific RadButton after the ApplicationThemeName has been set?

Looks like this has been addressed before, here is the solution:
