Post complex model to controller MVC using Facebook application template C# - facebook

Question

I have following model:
class HomePageModel
{
public User user { get; set; }
public ResultHistory resultHistory { get; set; }
public Option option { get; set; }
public HomePageModel()
{
}
}
Code from controller when passing it into view:
[FacebookAuthorize]
public async Task<ActionResult> Index(Context context)
{
ViewBag.AppUrl = GlobalFacebookConfiguration.Configuration.AppUrl;
if (ModelState.IsValid)
{
var user = await context.Client.GetCurrentUserAsync<MyAppUser>();
var option = new Option();
//CODE for reading user from db, simpified
Users dbUser = db.Get(context);
var resultHistory = new ResultHistory(dbUser.NSPGW, dbUser.NSPGL,
dbUser.NMPGW,dbUser.NMPGL,dbUser.NDPGW, dbUser.NDPGL);
HomepageModel homepageModel = new HomepageModel();
homepageModel.option = option;
homepageModel.resultHistory = resultHistory;
homepageModel.user = user;
return View(homepageModel);
}
}
Code from controller
#using (Html.BeginForm("Start", "Home", FormMethod.Post, new { id="opcijeForm"}))
{
<div class="row">
<div class="col-md-4">
<div class="radio">
<label>
<input type="radio" name="radio" value="sp" />SP
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="radio" value="mp" />MP
</label>
</div>
<div>
<input type="submit" value="start" />
</div>
</div>
<div class="col-md-8">
<div id="spoption">
#Html.DropDownListFor(m => m.option.sl, Model.option.slSelectList)
<label style="padding-left:10px">
<input type="checkbox" id="bb" /> BB
</label>
#Html.DropDownListFor(m => m.option.swt, Model.option.swtSelectList, new {id="bbdd" })
<label style="padding-left:10px">
<input type="checkbox" id="ziv" /> ziv
</label>
#* #Html.DropDownListFor(m => m.gameOption.sln, Model.option.slnSelectList, new { id="zivdd"})*#
</div>
<div id="mpoption">
<label>Numer of oppointment</label>
#Html.DropDownListFor(m=>m.option.spn, Model.option.spnSelectList)
#Html.DropDownListFor(m=>m.option.smv, Model.option.smvSelectList)
</div>
</div>
</div>
}
and receiving model on post
[FacebookAuthorize]
[HttpPost]
public ActionResult Start(HomepageModel model)
{
//Some code
//here is for example model.option null
}
When I submit form with above model, in my controller action where I receive same model, all it's properties are null.Each class that is within HomePage has only string and int as properties. If I move something, for example from class Option and put it in HomePageModel direct, then properties I have moved are not null. Is there a way to post model as above, or should I just copy properties from these three class into HomePageModel class?
[EDIT]
It is because of meta-data FacebookAuthorize, when I remove it everything is working
