卡片操作未运行Google脚本功能

Question

我似乎无法获得此卡上操作按钮的事件监听器来触发Google脚本中的功能

 <!-- AUTOS CARDS -->
    <section class="mdl-layout__tab-panel is-active" id="fixed-tab-1">
      <div class="page-content">          
<? for(var i=0; i<autosarray.length;i++){ ?>
  <div class="mdl-card mdl-shadow--2dp demo-card-square">
    <div class="mdl-card__title mdl-card--expand" <?!= autosarraySR[i]; ?>>
      <h2 class="mdl-card__title-text" id = "cate"><?= autosarray[i]; ?> </h2>
    </div>
    <div class="mdl-card__supporting-text">
      Last Run by <?= autosarrayU[i]; ?> <?= autosarrayT[i]; ?>
    </div>
    <div class="mdl-card__actions mdl-card--border">
      <a class="mdl-button mdl-button--colored mdl-js-button mdl-js-ripple-effect" id= "btnautos">
          Run Search 
        </a>
        <script>

document.getElementById("btnautos").addEventListener("click",sendback);

        function sendback(){
          var cate document.getElementById("cate").value;

          google.script.run.send(cate);
        }
        </script>
    </div>
  </div>
 <? } ?>
