Did you try "loader.setTranslationEnabled(true);" before loader.load?

I tried enabling setLanguageChangeEnabled(true) but I don't see my
label updating, do I have to write some handler for that event and go
through to update each widget text ? Apologies, I am new to translation.

It should automatically react to language change events, see:
