ASP.NET MVC - Submit Form with complex Model with EntitySet

I'm struggling myself trying to make my form work with my models...

So, I have 3 Models

Account
  has_one  -> Company
  has_many -> Individuals -> has_one Document

So the account can have one company and many individuals with one document each.

When submit my forms I have the following action

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult OpenAnAccount(string area, [Bind(Exclude = "Id")] Website.Model.Account account)
{
  var db = new DB();

  var type = new int();

  switch (area)
  {
      case "business": type = 1; break;
      case "private": type = 2; break;
  }

  if (ModelState.IsValid)
  {
      try
      {
         account.Type = type;
         db.Accounts.InsertOnSubmit(account);
         db.SubmitChanges();
         return View("OpenAnAccount/ThankYou");
      }
      catch
      {
         return View();
      }
  }
  else
  {
     return View();
  }    
}

And on my form simple things like

%label{for='companyName'} <em>*</em>Company Name
%input{class='required' id='companyName' name='Company.Name' type='text'}
%label{for='companyTradeName'}Trading As (if Different)
%input{id='开发者_如何学运维companyTradeName' name='Company.Trade' type='text'}
%label{for='companyRegistrationNumber'} <em>*</em>Company Registration Number
%input{class='required' id='companyRegistrationNumber' name='Company.Registration' type='text'}
%label{for='vatNumber'}VAT Number (if Applicable)
%input{id='vatNumber' name='Company.VAT' type='text'}

Which means I am naming the fields as Company.Name, Company.Registration, etc... and for the individuals I'm doing like this

%label{for ='firstName_0'} <em>*</em>First Name
%input#firstName_0.required.firstName{ name='Individuals[0].FirstName' type='text'}
%label{for='middleName_0'} Middle Name
%input#middleName_0{ name='Individuals[0].MiddleName' type='text'}
%label{for='lastName_0'} <em>*</em>Last Name
%input#lastName_0.required{ name='Individuals[0].LastName' type='text'}

as Individuals[0].FirstName, Individuals[0].LastName, etc

But what is happening is that I'm indeed getting the account generation with my company, but it's not working for the Individuals....its not doing anything with the database?

Anyone could help me on that?

I've checked some resources like this http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx but it doesn't work in my case I suppose, because it didn't change anything.

Thanks in advance

This answer seemed to be a straightforward way to do it: ASP.Net MVC - model with collection not populating on postback In case anyone needs it

I make a possible solution, look at this and tell me back what you think please...
