setValidity needs to be called on the ngModelController   Inside the controller  I think that means  scope myForm file  setValidity       See also section  Custom Validation  on the Forms page  if you haven t already     Also  for the first argument to  setValidity  use just  filetype  and  size

This line   myForm file  setValidity  myForm file  error size   false     Should be   scope myForm file  setValidity  size   false

A better and optimised solution to display multiple validation messages for a single element would be like this    lt div ng-messages  myForm file  error  ng-show  myForm file  touched  gt    lt span class  error  ng-message  required  gt   lt your message gt   lt  span gt    lt span class  error  ng-message  size  gt   lt your message gt   lt  span gt    lt span class  error  ng-message  filetype  gt   lt your message gt   lt  span gt   lt  div gt    Controller Code should be the one suggested by   Ben Lesh
