jQuery scroll function doesn't work

[anticHxCx]

Hello, how are you?

First of all I'd like to thank and praise your work, it was a great job!
I've been development a website using this pluggin but I have a problem.
I'm trying to use scroll function on page but I can't, anything happens, for example:

$(document).ready(function () {
$(".wrapper").scroll(function() {
alert('test');
});
});

Also I tried to use "$.(window)", other div objects, ID reference but anyone worked, besides that, I tried to change css style ".wrapper div { position: absolute..." but also didn't work.

Could you see if I've been doing something wrong?

Thanks a lot
