Triggered when a new date-range is rendered, or when the view type switches.
function( view, element )
view is the View Object for the new view.
element is a jQuery element for the container of the new view.
This callback will get triggered when the user changes the view, or when any of the date navigation methods are called.
This callback will trigger after the view has been fully rendered, but before events have been rendered (see also: eventAfterAllRender).
