Angular v1.5, Directive with class="{{className}}", addClass('extraClass') in link function doesn't work

[aarongan]

Hi,
I tried to inject extra className in link function using addClass method, i found a problem is when my directive has expression in class, the injection just ignore and no error message.
eg
directive with class="class-{{ id }}"

and in directive link function, i tried manually addClass('extraClassNam'), this extraClassName doesn't get injected into Dom element after link.

I noticed that, in link function phase, expression didn't get eval compare to previous version.

thanks,
Aaron

Continue my investigating...
This is happening in all attributes which i would believe is mechanism change.

Tried any attributes with expression in your template, and add attr('my-attribute', 'xxxx'), it wouldn't work unless i remove expression {{}} in the templates. =(
