我用ajax做分页，vue做数据渲染，当我点击第二页时请求数据这个是没有问题的，但是当我回到第一页，页面事件就不生效了，我要怎样删除页面数据重新渲染？？

<tbody>
                                <tr class="gradeX" v-for="(item,index) in mydatas">
                                    <td class="expand tabclick">{{item.id}}</td>
                                    <td class="">{{item.menuname}}</td>
                                    <td>{{item.engname}}</td>
                                    <td>{{item.path}}</td>
                                    <td data-hide="default,phone,tablet">{{item.ord}}</td>
