Render PartialView from background thread using SqlDependency

Question

I'm trying to update a PartialView when a register is updated in DataBase. I'm using SqlDependency and the event rise properly when the change happens.

SqlDependency.OnChange += new OnChangeEventHandler(sqlDependency_OnChange);

Method:

Private void sqlDependency_OnChange(object sender, SqlNotificationEventArgs e)
    {
        System.Diagnostics.Debug.WriteLine("Ok");

        UpdateView();

    }

And the method that is called:

 public ActionResult UpdateView()
    {
        try
        {
            //Blablabla...
            //Business logic...
            //Blablabla...
            model = 2;

            return PartialView(model);
        }
        catch (Exception ex)
        {
            return PartialView(0);
        }
    }

I receive every time a change is made the Lines in the OutputWindow, the method UpdateView() exits with no errors, but the PartialView is not render any more.

The View:

@model int
<h4>You have @Model points.</h4>

What I'm doing wrong? Is it because I'm requesting the Render from a different thread? Can I Update a View from server side when an event occurs? Thanks for your help!
