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

Since the value is from your main view model and you are calling your partial from the main view, just set the value of your model object in your constructor when you call the new S.Models.Post.

@Html.Partial("_AddPost", new S.Models.Post({wallPost = model.Value}))

If you have items in your ViewData or ViewBag from the main view, you can also pass those into the partial by adding a third parameter

@Html.Partial("_AddPost", new S.Models.Post(), ViewData)
