请问一下关于nodejs的问题,对象添加问题

Question

                    这里doc我已经用mongoose查询过来了已经有了如下：

        { _id: 5abde50b0bbd63c05201e938,

          productImage: '1.jpg',

          salePrice: 200,

          productName: '小米音响',

          productId: '201710007' }

                        if(doc){

//但是我这两个属性没有加上

                               doc.productNum = "1";

                               doc.checked = "1";

//但是我这两个属性没有加上

                               userdoc.cartList.push(doc);

                               userdoc.save(function(err2,doc){

                                   if(err2){

                                       res.json({

                                        status:'1',

                                        msg:err2.message

                                        })

                                    }else{

                                       res.json({

                                            status:'0',

                                            msg:"",

                                            result:"成功"

                                            })

                                    }

                                });

这是我的数据模型

var mongoose = require('mongoose');

var userSchema = new mongoose.Schema({

"userId":String,

"userName":String,

"userPwd":String,

"orderList":Array,

"cartList":[

{

"productId":String,

"productName":String,

"salePrice":String,

"productImage":String,

"checked":String,

"productNum":String

}

],

"addressList":Array

});

module.exports = mongoose.model("us",userSchema);

希望各位大师帮我解释下为什么
