vue中使用微信开放标签wx-open-subscribe 怎么在开放标签上添加事件并传参？

<wx-open-subscribe @success="success"   @error="subError" :template="subTemplateId"   id="subscribe-btn">
      <script type="text/wxtag-template">
        <style>
          button{
            border:none;
            padding:0;
            margin:0 auto;
            outline:none;
          }
          button:focus{outline:0;} 
          .return-bottom1{
            width: 100%;
            height: 45px;
            position: fixed;
            bottom: 0;
            left: 0;
            background: #ff5454;
            text-align: center;
            line-height: 45px;
            color: #fff;
            font-size: 16px;
            display:block;
          }
        </style>
        <button class="return-bottom1">提交</button>
      </script>
    </wx-open-subscribe>

p这个提交事件@click加在button 上面没有反应，并想在提交时进行item每一项传参
