JQuery Selector is not working for second time

JQuery Selector is not working for second time

Hi I am using JQuery for Selecting Divs having particular class name.
After it worked for first time fine I am not able to find same divs in
second requests.
Following is my code:\
$(document).ready(function () {
$("#hrefFareSorting").click(function () {
var divValues = $('.Flight_O').get();
alert(divValues);
disp(divValues, 0, '#divFlightPrice_O');
.......
I am using VS 2010 IDE and .NET runtime 4.0 and default jquery libs.
Any help is greatly appreciated.
Best Regards
Sudhir
