Disclose event never fires
===

I'm just about done with [this tutorial](http://miamicoder.com/2012/how-to-create-a-sencha-touch-2-app-part-5/). This part involves refactoring the code we wrote in part 4. I was able to get the app in a working state, but after refactoring, I can't select a note to edit. My list is created here:

    xtype: 'list',
    			store: 'Notes',
    			itemId: 'notesList',
    			loadingText: 'Loading Notes...',
    			emptyText: '<div class="notes-list-empty-text">No notes found.</div>',
    			onItemDisclosure: true,
    			grouped: true,
    			itemTpl: '<div class="list-item-title">{title}</div><div class="list-item-narrative">{narrative}</div>'

The listener is defined like this:

    {
    	delegate: "#notesList",
    	event: "disclose",
    	fn: "onNotesListDisclose",
    }

The onNotesListDisclose function is defined here:

    onNotesListDisclose: function(list, record, target, index, event, options) {
    	console.log('editNoteCommand');
    	this.fireEvent('editNoteCommand', this, record);
    }

Any help is appreciated!
