angular-bootstrap tabs插件为何获取不到ngmodel值。

Question

 <uib-tabset active="activeJustified" justified="true">
    <uib-tab index="0" heading="Justified">
      name
      <input type="text" ng-model="name"/>
    </uib-tab>
    <uib-tab index="1" heading="SJ">Short Labeled Justified content</uib-tab>
    <uib-tab index="2" heading="Long Justified">Long Labeled Justified content</uib-tab>
  </uib-tabset>
  <button type="button" ng-click="clicks()">点击</button>
  <hr />

点击后获取不到name的值，求大神
