ng提交未执行

我有以下形式：

<form  class="panel-body wrapper-lg" id="form_login"  ng-controller="UserController as userCtrl" ng-submit="userCtrl.test()">
    <div class="form-group">
        <label class="control-label">Brugernavn</label>
        <input type="email" class="form-control input-lg" id="txt_username" name="username" placeholder="Brugernavn" ng-model="userCtrl.user.username" >
    </div>
    <div class="form-group">
        <label class="control-label">Kodeord</label>
        <input type="password" name="password" placeholder="Kodeord" class="form-control input-lg" ng-required="" ng-model="userCtrl.user.password">
    </div>
    <input type="submit" class="btn btn-lb-primary" value="Log på">
</form>

这很简单。

现在我有以下控制器代码：

userModule.controller('UserController', ['$http', '$scope', function($http, $scope) {
  this.user = {
    username: "",
    password: ""
  };
  $scope.test = function() {
    alert($scope.user);
  }
}]);

现在，当我尝试提交表单时，test函数永远不会被调用。

有人能告诉我为什么吗？

更新我的代码

userModule.controller('UserController', ['$http','$scope', function ($http, $scope)
{
    var vm = this;
    vm.user =
    {
        username: "",
        password: ""
    };
    vm.test = function()
    {
        alert(vm.user);
    }
}]);

表单

    <form  class="panel-body wrapper-lg" id="form_login"  ng-controller="UserController as userCtrl" ng-submit="test()">
    <div class="form-group">
        <label class="control-label">Brugernavn</label>
        <input type="email" class="form-control input-lg" id="txt_username" name="username" placeholder="Brugernavn" ng-model="userCtrl.user.username" >
    </div>
    <div class="form-group">
        <label class="control-label">Kodeord</label>
        <input type="password" name="password" placeholder="Kodeord" class="form-control input-lg" ng-required="" ng-model="userCtrl.user.password">
    </div>
    <input type="submit" class="btn btn-lb-primary" value="Log på">
</form>
