fix(calendar): fire onchange only when date selection is complete

This PR allow to fire onChange only when a date selection if complete. For a datetime for example, onChange is called when a date is selected, then when a hour is selected, and again when minutes are selected... which is IMHO is a complete nonsense. If I apply a method when a date is changed, i'd prefer trigger this change only when i have finished to select my date...
