如何在bootstrap模式弹出窗口中调用角度函数

<button class="btn btn-primary" data-toggle="modal" data-target="#myModal">打开弹出窗口</button>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h4 class="modal-title" id="myModalLabel">弹出窗口标题</h4>
      </div>
      <div class="modal-body">
        弹出窗口内容
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
      </div>
    </div>
  </div>
</div>

function angularFunction() {
  // 在这里编写调用角度函数的代码
}

<button class="btn btn-primary" data-toggle="modal" data-target="#myModal" ng-click="angularFunction()">打开弹出窗口</button>
