Set onDateClear to default to two weeks vs actually clearing

#1

I have a datepicker (15 to be exact) which need the clear button on a daterangepicker to be set to 14 days in the past when clicked, is there a way we can do that? I have attached my snippit.

@intregal is the same thing achievable to make the clear button default to the current date on just a datepicker?
