jquery ui datepicker selecter issue

[efiJquery]

when using datepicker with the following selectors on the same page only one will get the value; ex: $("#mainContent #txtDate").datepicker({});

$("#secondContent #txtDate").datepicker({});

only the later will get the value which was selected.("#secondContent #txtDate")

It's invalid to have two elements with the same ID.
