dynamically adding table rows stop working after having selected a date from datepicker (missing attachment now added)

dynamically adding table rows stop working after having selected a date from datepicker (missing attachment now added)

Hi!
 
I have a page where I can add and remove table rows as well as select a date using the jquery datepicker. The page works just fine as long as I do not select a date. As soon as I have done so the adding (but not removing) of table rows stop working.
 
I have attached an html file that reproduces this strange behaviour.
 
Any and all help would be much appreciated. I'm a jquery newbie so I guess I have overlooked something simple.
