I have a form that looks like this:

using (Html.BeginUmbracoForm("SubmitStory", "NewsStorySubmitSurface"))
{
   <p>
     @Html.LabelFor(x => storyModel.Headline)  @Html.TextBoxFor(x => storyModel.Headline)
   </p>
   <p>
     @Html.LabelFor(x => storyModel.Standfirst)  @Html.TextAreaFor(x => storyModel.Standfirst)
   </p>
   <p>
     @Html.LabelFor(x => storyModel.Story) @Html.TextAreaFor(x => storyModel.Story)
   </p>
   <input type="submit" />
}

Now in my NewsStorySubmitSurface controller I have the following:

    public ActionResult SubmitStory(NewsStorySubmitModel model)
    {
        var newsStory = Services.ContentService.CreateContent(model.Headline, GetParentId(), "newsStoryType");
        // do stuff
     }

What I am noticing is that my the model parameter in the code is always coming in with empty properties. However, in the Request.Form list, all the properties exist.

Obviously, I can set them by hand, but why is Umbraco not doing this automatically? If I do @Html.EditorFor(storyModel) it also appears to pass down this empty model. I guess I'll have to get the posted values manually, but it seems like I shouldn't have to.
