vue如何动态更新外部引用对象?

Question

    function processData2(responseText) {
        var data = responseText;                         
        var docjson = data.List;        
        
        console.log("178: " + docjson[9].Title)        
    
        var vm = new Vue({
            el: '#docs',            
            data: {
                docjson: docjson,
            },
            methods:{
              showintro(infoId,infoType){
                 opennewpage(infoType + "intro.html?infoId=" + infoId, infoType + "intro", "slide-in-right", true, true);                    
              },                  
            }
        });                                        
    }

                </div>
            </div>

第一次加载后data能够获取到docjson 的值，并渲染到列表当中。但是上拉加载后，虽然docjson 里的值更新了，可是列表并没有跟着更新，依然是显示的是上一次的数据，是因为docjson 动态更新后没有传入到data里吗？

你是如何更新值得，直接docjson = ? 这样
