process for creating right-click context menu on grid using architect

Does anyone have a clue on what the process for adding a grid right-click context menu using architect? I can set it up just fine without architect.

I can add the context menu listener using architect resulting in the following:

in grid panel code

Code:

listeners: {
   itemcontextmenu: 'onGridpanelItemContextMenu'
},

in view controller code:

Code:

onGridpanelItemContextMenu: function(dataview, record, item, index, e, eOpts) { 
    e.stopEvent();
    mnuContext.showAt(event.xy);
},

Now how do i create the following custom menu attribute in my view controller?

Code:

var mnuContext =newExt.menu.Menu({    items:[{        id:'do-something',        text:'Do something'}],    listeners:{        itemclick:function(item){switch(item.id){case'do-something':break;}}}});

basically, how can/should I create any custom attribute/property inside a class managed by architect?

Thanks in advance for any help.
