Fix multi language feature

[Debatty-Tom]

Solve #71 using a closure to ensure the translation respects the current locale:

Each attribute now uses setAttribute with a closure that calls the translate method. The closures are only executed when the view accesses the attributes, ensuring that the current locale has already been set and translations are rendered correctly.

Good one!

However, could you add a comment on the getAttribute() method, indicating why closure are resolved when accessing the attribute? The idea is to explain the translations problem for future maintainers.
