asp.net ajax update panel not working

Question

Hi all

i am trying to call handler.ashx page on button click event with butten in ajax update panel , but handler code is not getting executed, but it needs to refresh the page.

here is the code : handler.ashx

public class Handler : IHttpHandler 
{
    getImageService.ScreenSenderClient cli = new getImageService.ScreenSenderClient();
    
    public void ProcessRequest (HttpContext context)
    {
        byte[] buffer = cli.GetImage();
        context.Response.Buffer = true;
        context.Response.BinaryWrite(buffer);
        context.Response.Flush();
        context.Response.End();
    }
}

and button and imagebox in ajax update panel

 Image1.ImageUrl = "~/Handler.ashx";

how ever the code in handler works only first time after i refresh page but not after that.
