Is there any callback event if I do something with spans ? like grid.addSpan()
I need a callback event if the span were update so I can refresh grid only then, or if there is something to compare with previous span and udpated spans
The thing is that in data components (e.g. datateble) all data are stored in the DataStore.
That means, that you could apply any DataStore events for the component.data.
Moreover, datatable also has it's own events, as onBeforeAdd, onBeforeDelete and other.
