dotnetnuke 7开发模块中的AngularJS形式

我正在使用AngularJS开发dotnetnuke 7模块。这是我在View.ascx中的代码：

<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<h2>Validation Example</h2>

<form  ng-app="myApp"  ng-controller="validateCtrl"
name="myForm" novalidate>

<p>Username:<br>
  <input type="text" name="user" ng-model="user" required>
  <span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
  <span ng-show="myForm.user.$error.required">Username is required.</span>
  </span>
</p>

<p>Email:<br>
  <input type="email" name="email" ng-model="email" required>
  <span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
  <span ng-show="myForm.email.$error.required">Email is required.</span>
  <span ng-show="myForm.email.$error.email">Invalid email address.</span>
  </span>
</p>

<p>
  <input type="submit"
  ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||
  myForm.email.$dirty && myForm.email.$invalid">
</p>

</form>

<script>
    var app = angular.module('myApp', []);
    app.controller('validateCtrl', function ($scope) {
        $scope.user = 'John Doe';
        $scope.email = '[email protected]';
    });
</script>

该代码是从W3School复制的，但是AngularJS似乎运行不正常。这是我的视图的屏幕截图：

我尝试了一个AngularSJ的简单示例，它的运行效果很好：

<div ng-app="" ng-init="firstName='John'">

<p>Name: <input type="text" ng-model="firstName"></p>
<p>You wrote: {{ firstName }}</p>

</div>

为什么我的第一段代码不起作用？我的模块中是否有关于“ form”标签的问题？
