Javascript functions not working on second page of ajax'd paging

The problem I am having is I have ajax paging implimented and I have 6+ javascript functions I want to preform on checkboxes etc... These javascript functions all work correctly when I am on the first page of the ajax'd paging, but when i goto the second one... the elements are considered undefined (i used an alert message to test it) I can't figure out why its doing this... I have done testing ... searched the web... but I can't figure out why the elements don't respond!!


Here is the outputed ajax'd page... on page 2, the page I am having trouble with... below this code is the javascript I am running on it...

(to many characters so i uploaded it in a text file)
