Angular's ng-blur on input field not working

Question

Ok, so I'm pretty sure I'm missing something obvious, but I'm not seeing it.

I created a fiddle that I would have thought would throw an alert message when the input box loses focus, but it's not working and I don't know why.

I was expecting an alert message when the user performs the following steps:

1. click the input box
2. type something
3. click somewhere outside of the input box

but these steps do not show an alert message.

Surely, someone knows what I'm doing wrong...?

Here's the code (same as the fiddle):

<div ng-app>
  <div ng-controller="MyCtrl">  
    <form name="myForm">
      <input type="text" ng-model="todoText" size="30"
         name="myInput" ng-blur="validate(myForm)">
    </form>
  </div>
</div>

function MyCtrl($scope) {
  $scope.validate = function(form) {
    alert('blur!');
  };
}

It could be your version of angular. Your fiddle is using 1.0.x I updated you to 1.4.x and its working fine:

<div ng-app='myApp'>
  <div ng-controller="MyCtrl">  
  {{santity}}
    <form name="myForm">
      <input type="text" ng-model="todoText" size="30"
             name="myInput" ng-blur="validate(myForm)">
    </form>
  </div>
</div>

Javascript

angular.module('myApp', []);
angular.module('myApp').controller('MyCtrl', MyCtrl);

function MyCtrl($scope) {
 $scope.santity = 'Hello';
 $scope.validate = function(form) {
  alert('blur!');
 };
}
