It would be very helpful to have more events on every controls and better event arguments on existing and future ones. This include things like click events that could be listened with a standard event binder with proper selector. We don't want to figure out what the selectors has to be. This would dramatically improve the customization of Kendo controls, which I find very hard to deal with in the current state.
You have the flexibility to bind, trigger and unbind events to widgets using the bind/trigger/unbind methods, respectively, as explained in the docs: http://docs.telerik.com/kendo-ui/api/framework/observable#bind Within the corresponding event handlers you can pass and handle arguments. Please refer to the pertinent event handlers documentation for more details.
