Hi @vstene. Thanks for your PR.

I've just take this project and I would like to know about your scenario. Could you please explain me why would be necessary? Would you mind creating a plunkr for me?

You can fork from this example though: http://plnkr.co/edit/1U8KCH?p=preview

Hello @leocaseiro,

I have a multi language app and I need to refresh the text attributes on language change. The problem seems to be that the attributes are not binded.

For example, when changing the scope variable the text is not updated:

From the current version of my fork the binding is applied via attr.$observe:

Hope this helps.

Hi @vstene thank you for your reply.

I liked it. I'm going to resolve some conflicts and them I'll accept your PR.

I just would remove the reference from chosen.set_default_text() which gives me a warning:

TypeError: Cannot read property 'set_default_text' of null

[leocaseiro]

So we don't need the methods disableWithMessage() and removeEmptyMessage() as the updateMessage() would work for both, right?

I created the branch 128-vind-placeholder-text-single which should fix your issue. I resolved all conflicts with the last PR's. Could you please double check if works for you?
So I'll merge into master and release 1.2.1 with this enhancement

Thanks

I don't remember the reason for the set_default_text(), but it seems to work now without.
