url.action, jquery, and mvc

I'm building an application that will shutdown a server, ping that server, and notify the user if the server has been shutdown. If it does not shutdown successfully, it allows the user to "Try Again". I can get the application to process the logic correctly the first time but when I implement the "Try Again" feature, it does not reprocess the Shutdown action. I think it must have something to do with caching but I don't know enough about it to know where to start looking. Any ideas?

Here is my code:

Controller

    //URL: Build/Progress  
    public ActionResult Progress()  
    {  
        return View();  
    }  

////URL: Build/MoveDevice  
public ActionResult ShutdownStatus()  
{  
    ImageInfo ImageInfo = new ImageInfo();  
    FarmInfo FarmInfo = new FarmInfo();  
    ProgressModel ProgressModel = new ProgressModel();  

    if ((Session["ShutdownStatus"] as string) == "Success")  
    {  
        ProgressModel.ShutdownStatus = 1;  
        return View(ProgressModel);  
    }  
    else  
    {  
        ImageInfo = svcImage.GetImageInfoByImageId(Session["ImageName"].ToString());  
        string Farm = ImageInfo.FarmId.ToString();  
        FarmInfo = svcFarm.GetFarmByFarmId(Farm);  
        svcImageSvc.ShutdownDevice(Session["Username"].ToString(), Session["Password"].ToString(), Session["Domain"].ToString(),  
            FarmInfo.farmName, ImageInfo.Device, ImageInfo.ImageHistory.Status, ImageInfo.PVSHost, ImageInfo.PVSAccount);  

        ProgressModel.ShutdownStatus = svcImageSvc.PingDevice(ImageInfo.Device);  
        return View(ProgressModel);  
    }  
}

I believe the caching is actually being done by jQuery. Change the $.get to a $.post and see if it works. If it does, you can still use $.get, but you will need to set the option:

cache: false
