How to do Validation with angular JS/ionic Framework

This validation doesn’t seem to work in latest version of ionic css v1.0.0-beta.14.

Problems:

  1. border-left & right doesn’t change to green after successful validation.
  2. textarea, select controls doesn’t hide the error icon even after entering data. This is the same in plunker posted by @Calendee (but in this example problem is only with textarea).

Help would be very much appreciated.
