Right Click Menu using React JS

UPDATE:

Figured it out – here is what you can do

var addMenu;

componentWillMount: function() {
    addMenu = new nw.Menu();
    addMenu.append(new nw.MenuItem({
        label: 'doSomething',
        click: function() {
            // doSomething
        }
    }));
},

contextMenu: function(e) {
    e.preventDefault();
    addMenu.popup(e.clientX, e.clientY);
},

render: function(){
    return <button onClick={this.handleClick} onContextMenu={this.contextMenu}>SomethingUseful</button>
}

In render you can pass a function to onContextMenu for when a right click occurs for this react component.
