Where should view events live if not using ExtJS MVC architecture?
===

When using the Sencha ExtJS framework, the events for your view live inside of the controller for that view.  If you're not using a controller, where do you store the events.  

For example, suppose our MVC application, we have a grid of users (userlist), and we have an event "itemdblclick".  How would we implement "itemdblclick" inside of our non-MVC application?

    Ext.define('AM.view.user.List' ,{
        extend: 'Ext.grid.Panel',
        alias: 'widget.userlist',
        title: 'All Users',
    
        // we no longer define the Users store in the `initComponent` method
        store: 'Users',
    
    ...
            
    });



    Ext.define('AM.controller.Users', {
    	extend: 'Ext.app.Controller',
    	stores: ['Users'],
    	models: ['User'],
    
    	views: [
    		'user.List',
    		'user.Edit'
    	],
        
    	init: function() {
    		this.control({
    			'viewport > userlist': {
    				itemdblclick: this.editUser
    			},
    			'useredit button[action=save]': {
    				click: this.updateUser
    			}
    		});
    	},
    
    	editUser: function(grid, record) {
    		var view = Ext.widget('useredit');
    		view.down('form').loadRecord(record);
    	},
    	
    	updateUser: function(button) {
    		console.log('clicked the Save button');
    
    		var win = 
    			button.up('window'),
    			form = win.down('form'),
    			record = form.getRecord(),
    			values = form.getValues();
    
    		record.set(values);
    		win.close();
    
    		// synchronize the store after editing the record
    		this.getUsersStore().sync();
    	}
    
    });
