Changing style

[TiSer]

I want to add error class to bs-datetimepicker.
I can't bind it, because we have no class or style property, and when I'm trying to set class for div, inside which located bs-datetimepicker - it cause no effect.

Example:

.time
  bs-datetimepicker date=startedAtTime minDate=minDate

So, styles with color and border-color from .time class doesn't apply to datetimepicker.
