angularjs – Angular ng-model在编辑时设置为undefined

我正在创建一个模态对话框,并在对话框关闭时尝试读回字段,但是当编辑输入时,输入字段的ng-model被设置为undefined.使用 Plunk,如果单击对话框按钮然后按确定而不修改文本字段,则会显示“blah”.但是如果根本修改文本输入,则不会显示任何内容.

对话框模板是：

<script type="text/ng-template" id="simpleModal.html">
    <div class="modal-header">
      <h3 class="modal-title">Simple Modal</h3>
    </div>
    <div class="modal-body">
      <div class="form-group">
        <label for="emailInput">Email</label>
        <input id="emailInput" type="email" class="form-control" ng-model="user.email">
      </div>
    </div>
    <div class="modal-footer">
      <button class="btn" type="button" ng-click="ok()">Ok</button>
    </div>
  </script>

模态对话框的控制器：

app.controller('SimpleModalController',function($scope,$uibModalInstance,$log) {

  $scope.user = {
    email: "blah"
  };

  $scope.ok = function() {
    $log.debug('simpleModal ok called ' + $scope.user.email);
    $uibModalInstance.close($scope.user.email);
  };

});

我已经看到了对https://stackoverflow.com/a/22768720/552936的引用,但是我已经改变了我的代码以反映这一点并且它没有解决问题.

<input id="emailInput" type="email" class="form-control" ng-model="user.email">

<form name="myForm">
  <input type="email" name="myEmail" model="myEmail" />
  <span>Valid Email {{myForm.myInput.$valid}}
</form>
