Need to override the keyup function with a home grown function

I have a jqGrid validation methodology that's killing performance, due to the fact that the validateDuplicates function is being injected into the keyup event. I want to use my own function which would only return true if a duplicate is found, and at that point a performance hickup is okay.

Can someone tel me how to make up my own function, and make it chainable?

Right now I have this:
$('[id^="Container_"]).keyup(validateDuplicates).change(validateDuplicates);

I need (at least I think I need) to write an alternative to keyup, call it displiatesFound. And in there I'd add each barcode to a list, after checking if it already existed. If it did exist, two duplicates are found.

Thanks!

why don't you simply unbind the keyup event and see what happens?

But then what action (or event) would call the jquery default error code?

Here's what I was going to do. Please tell me if this will work. Oddly, it seems to and I have not yet even created my own duplicates test. I planned to insert it inside the anonymous function I created.

$('[id^="Container_"]).keyup(function () {
     validateDuplicates()
}).change(validateDuplicates);

What do you think?

I think my code unbinded it in a different way. Thanks.
