点击事件不火

Question

我试图在BackBone上触发click事件，但是没有得到任何事件， 看起来我确实选择器是正确的，但仍然无法让它工作，thnx寻求帮助！ 我的代码是：

  events: {
      "click #search_button": "doSearch"
    },
    doSearch: function (event) {
      // Button clicked, you can access the element that was clicked with event.currentTarget
      alert("Search for " + $("#search_input").val());
    }
  });

  var search_view = new SearchView({el: $("#search_container")});
  search_view.delegateEvents();

模板：

<div class="jumbotron" id="search_template">
  <div class="container">
    <div class="row">
      <div class="col-lg-6">
        <div class="input-group">
          <input type="text" class="form-control" placeholder="Search for..." id="search_input">
  <span class="input-group-btn">
    <button class="btn btn-default" id="search_button" type="button">Go!</button>
  </span>
        </div><!-- /input-group -->
      </div><!-- /.col-lg-6 -->
    </div><!-- /.row -->

  </div>
</div>
<div id="search_container"></div>
