How to Delete controller ExtJS?

Question

I dynamically create controllers in my application like this:

var loadedController = me.app.getController(controller_name);
            loadedController.init();

How can I delete this controller after using? Thanks.

ExtJs currently does not support removal of controllers out of the box. To cleanup a controller, do the following:

• Extend Ext.app.EventBus with a method uncontrol that unregisters all event listeners that this controller registered on the EventBus. Check out the source of Ext.app.EventBus#control to derive an implementation. Or use this one.
• Extend Ext.app.Application with a method removeController that removes a given controller instance from the controllers collection. It's a Ext.util.MixedCollection, check out the source for Ext.app.Application#getController. Then clean up all registered listeners for that controller using uncontrol.
• Implement a destroy method either on your specific controller and/or extend Ext.app.Controller. You should at least call clearManagedListeners() and possibly destroy other objects created by this controller like views or stores, if that suits your application architecture and controller life-cycle.
