In case anyone else looking for additional "enter" keypress support, here's an update to the fiddle provided by Gloppy

Code for keypress binding:

elm.bind("keydown keypress", function(event) {
    if (event.which === 13) {
        scope.$apply(function() {
            ngModelCtrl.$setViewValue(elm.val());
        });
    }
});

Override the default input onChange behavior  call the function only   when control loss focus and value was change       NOTE  ngChange is not similar to the classic onChange event it firing   the event while the value is changing This directive stores the value   of the element when it gets the focus    On blurs it checks whether the   new value has changed and if so it fires the event       param  String  - function name to be invoke when the  onChange    should be fired       example     lt  input my-on-change  myFunc   ng-model  model  gt    angular module  app       directive  myOnChange   function           return           restrict   A           require   ngModel           scope                myOnChange                         link  function  scope  elm  attr                if  attr type      radio     attr type      checkbox                     return                               store value when get focus             elm bind  focus   function                      scope value   elm val                                     execute the event when loose focus and value was change             elm bind  blur   function                      var currentValue   elm val                    if  scope value     currentValue                        if  scope myOnChange                            scope myOnChange

This post shows an example of a directive that delays the model changes to an input until the blur event fires   Here is a fiddle that shows the ng-change working with the new ng-model-on-blur directive  Note this is a slight tweak to the original fiddle   If you add the directive to your code you would change your binding to this    lt input type  text  ng-model  name  ng-model-onblur ng-change  update      gt    Here is the directive      override the default input to update on blur angular module  app       directive  ngModelOnblur   function         return           restrict   A           require   ngModel           priority  1     needed for angular 1 2 x         link  function scope  elm  attr  ngModelCtrl                if  attr type      radio     attr type      checkbox   return               elm unbind  input   unbind  keydown   unbind  change                elm bind  blur   function                     scope  apply function                         ngModelCtrl  setViewValue elm val                                                                           Note  as  wjin mentions in the comments below this feature is supported directly in Angular 1 3  currently in beta  via ngModelOptions  See the docs for more info

This is about recent additions to AngularJS  to serve as future answer  also for another question    Angular newer versions  now in 1 3 beta   AngularJS natively supports this option  using ngModelOptions  like   ng-model-options    updateOn   default blur   debounce    default  500  blur  0        NgModelOptions docs  Example    lt input type  text  name  username         ng-model  user name         ng-model-options   updateOn   default blur   debounce   default  500  blur  0       gt

For anyone struggling with IE8  it doesn t like the unbind  input    I found a way around it   Inject  sniffer into your directive and use   if  sniffer hasEvent  input         elm unbind  input        IE8 calms down if you do this

I had exactly the same problem and this worked for me  Add ng-model-update and ng-keyup and you re good to go  Here is the docs    lt input type  text  name  userName           ng-model  user name           ng-change  update             ng-model-options    updateOn   blur              ng-keyup  cancel  event     gt

According to my knowledge we should use ng-change with the select option and in textbox case we should use ng-blur
