怎样监听vue.js中v-for全部渲染完成？

<ul id="demo">
    <li v-for="item in list">{{item}}</div>
</ul>
...

new Vue({
    el:'#demo',
    data:{
        list=[0,1,2,3,4,5,6,7,8,9,10]
    },
    methods:{
        push:function(){
            this.list.push(11);
            this.nextTick(function(){
                alert('数据已经更新')
            });
            this.$nextTick(function(){
                alert('v-for渲染已经完成')
            })
        }
    }
})
