Imagine a simple Action with a post

```
public ActionResult Unsubscribe(string contentId)
{
    // get db content and translate it to the UnsubscribeViewModel
    UnsubscribeViewModel model = 
        myRepository.FindUnsubscribeContentById(contentId).ToUnsubscribeViewModel();

    // pass model into the view
    return View(model);
}

[HttpPost]
public ActionResult Unsubscribe(UnsubscribeViewModel model)
{
    // let's convert into DalModel
    UnsubscribeModel m = model.ToUnsubscribeModel();

    // let's save into the db
    myRepository.UpdateUnsubscribe(m);

    // because I'm using 2 models, let's get the new ID 
    // and append to he View model
    model.FieldId = m.unsubscribe_id;

    // let's return the new model to the View
    return View(model);
}

```

**my current problem is**, even if I do a breakpoint on the `return View(model)` line, **I DO HAVE** the `model.FieldId` **correctly assigned**, but in the HTML Page, I have the original value (in this case a `0` because there was no prior ID, it's a new record)

in the View I tried:

```
<%: Html.HiddenFor(x => x.FieldId) %>

```

and

```
<%: Html.Hidden("FieldId", Model.FieldId) %>

```

and they still have "0" as the value, like

```
<input type="hidden" value="0" name="FieldId" id="FieldId">

```

if I refresh the page, my Action fetch the new data and the value is changed to the correct id. But if I use `RedirectToAction("Unsubscribe")` I will loose the data and can't pass a Success/Error message trough `ViewData`, I have to use `RedirectToAction("Unsubscribe", new { something = msg })` and I don't want this way.

**Why is the View loading the original value instead the newly updated value from the Model?**

Thank you.
