datatables中的button触发modal事件

datatables中的button

<td>
<button type="button" data-toggle="modal" data-target="#editor" data-whatever={{ script.name }} class="btn btn-info" style="margin-right: 5px;">查看</button>
<button type="button" class="btn btn-warning" style="margin-right: 5px;">编辑</button>
<button type="button" class="btn btn-danger">删除</button>
</td>

{{ script.name }}是django的queryset
data-whatever绑定数据库数据通过modal的relatedTarget获取绑定数据

modal

<div class="modal fade" id="editor" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">查看脚本</h4>
      </div>
      <div class="modal-body">
      <form class="form-horizontal">
        <div class="form-group">
          <label for="scriptname" class="col-sm-2 control-label">脚本名称:</label>
          <div class="col-sm-10">
            <input type="text" class="form-control" id="scriptname" placeholder="unknown" readonly>
            <textarea id="cm" name="cm">test 4 chenqian.</textarea>
          </div>
        </div>
      </form>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

<script type="text/javascript">
  $(document).ready(function(){
    $('.btn-info').click(function () {
      $('#editor').on('shown', function(){
        alert("opened");
        var textarea = document.getElementById('cm');
        setTimeout(function(){
          var editor = CodeMirror.fromTextArea(textarea, {
            mode: 'text/css',
            lineNumbers: true,
            lineWrapping: true
          });
        }, 500);
        alert("code init");
      }).on('hidden', function(){
        editor.refresh();
      });
    });
  });
</script>

此时可以正常弹出modal窗口，但是alert/console.log并无任何反应。
