Javascript Treeview OnNode已选择未启动

我在用乔恩·迈尔斯的树景

我已经生成了一个JSON数据结构，treeview显示得很好，但是我无法启动onNodeSelected事件

您正在初始化节点2次。。 应该是这样的

 $(function () {

        var defaultData = @Html.Raw(broadcaster.GetTreeViewData()); //Getting data from C# data structure 



           $('#tree').treeview({

                color: "#428bca",
                data: defaultData,
                levels: 2,
     onNodeSelected: function(event, data) {
                alert('selected:')
            }
            });
        });

<li>
   <div id="tree"></div>
</li>

$('#tree').on('nodeSelected', function(event, data) {
        alert('selected:')

 $(function () {

        var defaultData = @Html.Raw(broadcaster.GetTreeViewData()); //Getting data from C# data structure 



           $('#tree').treeview({

                color: "#428bca",
                data: defaultData,
                levels: 2,
     onNodeSelected: function(event, data) {
                alert('selected:')
            }
            });
        });
