How to use Element ui pagination with Vue JS and Laravel

I'm trying to use element ui pagination with Vue JS and Laravel. It's not changing the data when I clicked next or prev. How to use it properly?

<tbody>
 <tr  v-for="post in posts | limitBy count offset">
     <td>{{post.id}}</td>
     <td>{{post.title}}</td>
     <td>{{post.body | trunCate}}</td>
     <td v-if="timeLang == 'en'">{{post.created_at | formatDateEn}}</td>
     <td v-else-if="timeLang == 'id'">{{post.created_at | formatDateId}}</td>
     <td><router-link :to="'/' + $route.params.trans + '/adminspace/' + post.post_id"><a 
     class="btn btn-default" >View</a></router-link></td>
     </tr>
     <tr v-if="!dataPost">
     <td>No result</td>
 </tr>
 </tbody>
 </table> 
 <div class="text-center">

 <el-pagination
 @current-change="handleCurrentChange"
 :current-page="current_page"
 :page-size="per_page"
 layout="prev, pager, next"
 :total="total">
 </el-pagination>
 </div>

 export default {
    data()
   {
      return {
          posts: [],
          timeLang: this.$route.params.trans,
          search: '',
          dataPost: true,
          per_page: null,
          current_page: null,
          total: null,
          next_page_url: null,
      }
  },
  created(){
    this.fetchPost();
  },
  methods: {
      fetchPost() {
      axios.get('/' + this.$route.params.trans + '/adminGetPosts')
      .then(({data}) => {
          this.posts = data.data
          this.current_page= data.current_page
          this.per_page = data.per_page
          this.total = data.total
          this.next_page_url = data.next_page_url
      })
      },
      searchPost() {
      axios.get('/' + this.$route.params.trans + '/adminSearchPost?search=' + this.search)
      .then(({data}) => {
          this.posts = data
          if(this.posts == '') {
              this.dataPost = false;
          } else {
              this.dataPost = true;
          };
          })
      },
      handleCurrentChange(val) {
          this.currentPage = val;
          console.log(`current page: ${val}`);
      }
      
  }
