inst is undefined error in jquery datepicker in a lightview

I basically have a jquery datepicker in a lightview. The datepicker shows
up but it doesnt seem functional as it does nothing when a day is
selected. It doesn't work and previous and next are selected as well.
I get the "inst is undefined" error
-- the script
jQuery(function() {
jQuery("#datepicker1").datepicker();
});
-- the element
<input type="text" id="datepicker1" name="datepicker1"/>
