骨干不是JSON解析正确

我传递给我的骨架模型JSON对象。我在骨干模型中有一个解析函数来转换一些传入的属性。问题是当我获取这个模型时，这些属性没有被分析，只是添加到模型中。底部的图像显示，不是将密码转换为密码而是删除密码，它只是将密码添加到对象的属性中。

这里是我的代码：

JSON

当我使用邮递员打电话给我的web服务，我得到了响应：

{"type":null,"idTeacher":1,"name":"Sean","password":"tst","email":null,"dob":1392940800000}

型号：

window.Teacher = Backbone.Model.extend({ 
    urlRoot: "http://localhost:8080/SIMS/resource/teacher", 
    defaults: { 
      "id": null, 
     "Name": "", 
     "Password": "", 
     "email": "", 
     "dob": "", 
     "type": "" 

     }, 

      parse: function(response){ 
       response.id = response.idTeacher; 
       response.Password = response.password; 
       response.Name = response.name; 
       delete response.name; 
       delete resoponse.password; 
       delete response.idTeacher; 
       return response; 
      } 
}); 

window.TeacherCollection = Backbone.Collection.extend({ 
    model: Teacher, 
    url: "http://localhost:8080/SIMS/resource/teacher", 

     parse: function(response){ 

      return response; 

     } 

});

Main.js //这是

before: function(callback) { 
     if (this.teacherList) { 
      if (callback) callback(); 
     } else { 
      console.log('........................................javascript........'); 
      this.teacherList = new TeacherCollection(); 
      console.log('Loading List: Size: ' + this.teacherList.length); 
      this.teacherList.fetch({success: function() { 
       console.log('........... ftech success...........'); 
       $('#contents').html(new TeacherListView({model: app.teacherList}).render().el); 
       if (callback) callback(); 
      }}); 
     } 
    }

如果调试我的骨干，我可以看到我的解析没有任何分析的变量和解析删除通话也不能工作。
