AngularUI Datepicker dynamic date disabling

I am using the AngularUI datepicker. I have two datepickers that influence each other. One is for example a "start date" and the other is an "end date". Instead of creating validation for both datepickers, I want to eliminate the option of having invalid dates (i.e. end date earlier than the start date and vice versa). Is there a way to re-trigger the date-disabled attribute on select of a date? (re-trigger the date-disabled of the OTHER datepicker) My plunkr: I have a start and end date, as you can see when you open each date picker, you cannot pick a start date higher than the end date and vice versa. However if I change my start date to 11/21, I want the end date's datepicker to update so that the 11/20 is no longer clickable. Is there any way to do this? http://plnkr.co/edit/TgisJnSwQItDeCuIReLL?p=preview
