Callback when a view's type or dates change (viewChange?)

The viewRender callback is called every time a view’s DOM is rendered/rerendered. It gets fired on a view’s initial render, but it also gets fired when a dynamic options change occurs that requires a view rerender. Or potentially for other reasons.

However, there is no callback that gets fired exclusively when there is a view-switch or the date-range change.

A common usecase: want to do post-processing on the DOM of the fc-title element at the top of the calendar, which is dependent on the date range but independent of the view.

Potential names for this callback: viewChange ?

Question: what if the view’s type changes (ex: agenda->basic), but the date range does not. should it still fire?

In the v5 release candidate this is called datesSet

In the v5 release candidate this is called datesSet

datesSet callback is not working in my case.
