Textbox change event doesn't fire the first time when testing on the Test server by the users. It works fine when I test on the Test Server.

Textbox change event doesn't fire the first time when testing on the Test server by the users. It works fine when I test on the Test Server.

I am using the following Code to invoke change event.

$( "#<% = txtBox.ClientID %>" ).change( function () {

SetText();

});

 

This code works fine in debug environment and on the test server when I test it. It doesn't work for other users the first time they change the text. It works the second time.
I am using JQuery 1.4.1(again, it works fine for me)
