Trouble with "mouseup" once DOM has been updated

I am writing a function that will be triggered every time I release the mouse(mouseup) from a inside a table row. This is accomplished using jquery: $('textarea').mouseup(function (e){ ...code }); Everything works fine except for when I add a new row to the table. Once I add the new row, i seems that the mouseup event is not detected. See the code in the link and do the following: 1. Write some text in the Col2 or Col3 2. Highlight the text. Expected: An alert will be shown with the text. 3. Press Add Row button, write something and highlight the text. The expected alert is not shown.

JsFiddle

Thanks!
