Datepicker not spawning any more after ajax rewrite of a table row

I have a table. Every table row has its own id. In the table row I have an "input type text" tag. Every "input type text" tag has its own id. With $.ajax I succesfully replace a row. The replaced row will bring the "input type text" tag with the same id it has before replacing. On this "input type text" tag the datepicker does not spawn anymore...

I tried to remove the datepicker from the "input type text" tag just before the ajax call and, soon after the succesful substitution, re-attach the datepicker to the "input type text" tag but nogthing happened...
