Couldn't get pageUnload() to be called.

public static int RefreshSession() {
HttpContext.Current.Session["Name"] = "BSD";
Configuration config = WebConfigurationManager.OpenWebConfiguration("~/Web.Config");
SessionStateSection section = (SessionStateSection)config.GetSection("system.web/sessionState");
int timeout = (int)section.Timeout.TotalMinutes * 1000 * 60;

I tried this link to generate verification Image [URL] ..... It works fine.
But I'd like to put a button in page for regenerating captcha for example. When the image was unreadable for user.
So I put an updatepanel in page and this is my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<tr> <td colspan="2">
<asp:Image ID="imCaptcha" ImageUrl="~/Captcha.ashx" runat="server" />
[Code] .....
Although the image changes but the whole page is refreshed. Whether this is due to incompatibilities httphandler and updatepanel?
I am using a datalist which contain image buttons. I want to know to selecte item in datalist in javascript.
