I'm writing a website in Umbraco 4.11.0 using MVC and I'm trying to add a form to a page, so far I've learnt almost everything from the MVC documentation on this page: http://our.umbraco.org/documentation/Reference/Mvc.

To create the form I've assumed that I need to use a custom controller in order to handle everything when submitting the form etc, I've used this page to help me in that respect: http://our.umbraco.org/documentation/Reference/Mvc/custom-controllers but I keep recieving an error when loading the page, the error is 

The model item passed into the dictionary is of type 'Umbraco.Web.Models.RenderModel', but this dictionary requires a model item of type 'MyMvcApp.Models.StatusViewModel'.

I'm using

@model MyMvcApp.Models.StatusViewModel

on the partial view and I've also tried using

@inherits Umbraco.Web.Mvc.UmbracoViewPage<MyMvcApp.Models.StatusViewModel>

but it gives the same error!

My Partial contains the following code:

@model MyMvcApp.Models.StatusViewModel

<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm(new { enctyp = "multipart/form-data" }))
{
    @Html.AntiForgeryToken("StatusViewForm")
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>StatusViewModel</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.StatusText)
        </div>
        <div class="editor-field">
            @Html.TextAreaFor(model => model.StatusText)
            @Html.ValidationMessageFor(model => model.StatusText)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Files)
        </div>
        <div class="editor-field">
            <input type="file" multiple name="Files" id="Files" />
            @Html.ValidationMessageFor(model => model.Files)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

And my Controller:

using MyMvcApp.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MyMvcApp.Controllers
{
    public class StatusController : Umbraco.Web.Mvc.RenderMvcController
    {
        //
        // GET: /Status/

        [HttpGet]
        public PartialViewResult Index()
        {
            return new PartialViewResult();
        }

        [HttpPost]
        [ValidateAntiForgeryToken(Salt="StatusViewForm")]
        public PartialViewResult Index(StatusViewModel model)
        {
            if (ModelState.IsValid)
            {

            }
            return new PartialViewResult();
        }
    }
}

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;

namespace MyMvcApp.Models
{
    public class StatusViewModel
    {
        [Required]
        public string StatusText { get; set; }
        public IEnumerable<HttpPostedFileBase> Files { get; set; }
    }
}
