[jQuery] Complex selector: bug on IE

Hello,
I have a problem with jquery 1.2.6 and IE (6 and 7). When I use this
code : http://pastebin.me/4986d5d6f219d it doesn't work on IE. Well,
it works but just the first time.
It's like the jquery object contains just the first element, not every
*[id^='MULTI-EXPERIENCE-'][id$='-EXPERIENCE_EN_POSTE_1'] elements...
Do you have a solution?
Thanks.
