PartialViews display not updated model

Question

I have problems with PartialViews using ASP.NET MVC3 (Razor) and Ajax. This is my case:
I have simple test viewmodel:

public class MyModel
{
    public string MyText { get; set; }
    public int MyNumber { get; set; }
}

My target is to have a form. Depending on posted data I would like to display different partial views. I've created main form (Index view):

@using (Ajax.BeginForm("Index", "Test", new AjaxOptions() { HttpMethod = "POST", UpdateTargetId = "testdiv" }))
{
    <div id="testdiv">


        @Html.Partial("Cat")

    </div>
    <input type="submit" value="Go" />
}

I've created two different partial views which should be shown when main form posted (depending on posted data): Cat View:

<span>cat view</span>
@Html.TextBoxFor(m=> m.MyText)
@Html.TextBoxFor(m=> m.MyNumber)
<span>@DateTime.Now.Second</span>

Dog View:

<span>dog view</span>
@Html.TextBoxFor(m=> m.MyText)
@Html.TextBoxFor(m=> m.MyNumber)
<span>@DateTime.Now.Second</span>

My controller contains four actions:

[HttpGet]
public ActionResult Index()
{
    MyModel model = new MyModel();
    return View(model);
}


[HttpPost]
public PartialViewResult Index(MyModel model)
{
    if (model.MyNumber == 1)
    {
        return Cat(model);
    }
    else
    {
        return Dog(model);
    }
}

[HttpPost]
public PartialViewResult Cat(MyModel model)
{
    model.MyText = model.MyText + " K";
    return PartialView("Cat", model);
}

[HttpPost]
public PartialViewResult Dog(MyModel model)
{
    model.MyText = model.MyText + " P";
    return PartialView("Dog", model);
}

My problem is that when Cat or Dog action is performed, MyText in model is changed, but when correct partial view is displayed I see old (not updated) MyText. Why? Any other ideas how to show a specific partial view depending on data posted in the form are welcome.

I refresh my partial views a little differently. I would use an ajax call on a button click instead of post back and pass the partial view that you want returned

$('.btnSubmit').on('click', function(){
    $.ajax({
        url: "@(Url.Action("Action", "Controller"))",
        type: "POST",
        cache: false,
        async: true,
        data: { type: 'cat/dog' },
        success: function(result){
            $('.Content').html(result);
        }
    });
});

Hopefully this will work for you.

i'm using it as jQuery ajax way same as you but problem is exist. That is updated about added or removed items but not for items that changed just in content. I don't know why. That is confused me. :( You can see my question about that in http://stackoverflow.com/questions/23033242/send-partial-view-model-and-update-partial-view-with-jquery-has-issues – QMaster Apr 13 '14 at 19:22
