Update input on blur - Angular

update_input_on_blur.coffee

# Only update <input> elements with bound angular models <input ng-model="my model"> on 'blur' event.
# Tweaked from a variety of places.
app.directive 'updateOnBlur', ->
  require : 'ngModel'
  link : (scope, element, attributes, ngModelController) ->
    element.unbind 'input'
    element.bind 'blur', ->
      scope.$apply ->
        ngModelController.$setViewValue element.val()

Note: this was before ng-model-options!
