Datepicker modifying the URL

Datepicker modifying the URL

I have a model dialog that allows the user to enter a date.

Here is a simplified version http://jsbin.com/ohisa3/1#weston

If I open this page is IE8 and select a date from the date picker. 

The URL changes from http://jsbin.com/ohisa3/1#weston to http://jsbin.com/ohisa3/1#


is there a way to stop the datepicker from changing the URL?
