Create a customized Node class with clickNode event handler

• Would like to create a node. If you click or select the node, there will be a message in the console.
• Here are the codes used. 

nx.define('MyExtendNode', nx.graphic.Topology.Node, {
    view: function(view) {
         view.content[2].events.clickNode = this._nodeClick;
         return view;
    },
    methods: {
        init: function(options) {
            this.inherited(options);
        },
        dispose: function() {
            this.inherited();
        },
        _nodeClick: function(sender, event){
            console.log('node clicked')
        }
    }
}); 

• But there is no message in console. Want to create a customized Node class.

About your customized node class, you should do two small modification. 

1. view.content[2].events.clickNode should be view.content[2].events.click 

2. Because NeXt view engine will parse the view json. So you should follow the syntax of view definition. like:

view.content[2].events.click = "{#_nodeClick}"

Check out the below example for your reference.
