Another simple contextmenu

Hi

I previously posted a thread asking about a contextmenu, however, here's another for you.

Code:

        <!-- Begin ExtJS-->
        <script type="text/javascript" charset="utf-8" async defer>
        Ext.BLANK_IMAGE_URL = 'ext-4.2.1.883/resources/images/default/s.gif';
        Ext.onReady(function(){
            console.log("Congratulations!  You have Ext configured correctly!");
            var removeAction = Ext.create('Ext.Action', {
    icon:'img/star_red.png',
    text: 'Remove this element, because I don\'t like it',
    handler: function(widget, event) {
        if(confirm("This element will be removed from DOM. You will need to refresh your browser to make it reappear. Continue?")) {
            Ext.get("elementContextMenu").remove();    
        }
        return false;
    }
});

var contextMenu = Ext.create('Ext.menu.Menu', {
    items: [
        removeAction
    ]
});
Ext.get("elementContextMenu").on("contextmenu", function(event,element){
    event.stopEvent();
    console.log(contextMenu.showAt(event.getXY()));
    return false;
})
        }); //end onReady
        </script><div style="padding:15px;background:#EEE;border:3px solid #AAA;border-radius:10px;color:#000;width:500px;margin:50px" id="elementContextMenu">Right click here</div>

When I right click the div, nothing happens??
