[jQuery] jquery combobox

Hello all,
I used this
http://jquery.sanchezsalvador.com/samples/example.htm
script for a while but now i use a newer version of jquery and it
doesnt work anymore
i get this kind of errors
'Syntax error, unrecognized expression: [@dataValue='Aanval']'
Could someone have a look at that script and tell me how it can work
again
Thx,
