avalon.serialize出来的form为空字符串，而jQuery的serialize出来的结果是对的

[winterwhisper]

html

<form ms-controller='article_form' ms-on-submit='articleAction'>
  <input type="hidden" ms-duplex='id'>
  <label for="title">title</label>
  <input type="text" id='title' name='title' ms-duplex='title'>
  <br>
  <label for="content">content</label>
  <textarea id="content" name='content' cols="60" rows="10" ms-duplex='content'></textarea>
  <br>
  <button>submit</button>
</form>

js

// ...
  var articleFormModel = avalon.define('article_form', function(vm) {
    vm.id = "";
    vm.title = "";
    vm.content = "";

    vm.articleAction = function(e) {
      avalon.post(vm.id == "" ? '/api/articles' : '/api/articles/' + id, 
                  avalon.serialize(this));
      e.preventDefault();
    };
  });
//...

请问是怎么回事呢？
