[Bind(Include = does not work with collection - asp.net

Question

I have a controller that looks like below:
public async Task<ActionResult> CreateProduct([Bind(Include = "Id,MyCollection")] MyClass myClass)
and this is the view:
<div class="form-group">
#Html.LabelFor(model => model.Id, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Id)
#Html.ValidationMessageFor(model => model.Id)
</div>
</div>
<table>
<tr>
<th>#Html.LabelFor(model => model.MyCollection.First().A)</th>
<th>#Html.LabelFor(model => model.MyCollection.First().B)</th>
<th>#Html.LabelFor(model => model.MyCollection.First().C)</th>
</tr>
#foreach (var item in this.Model.Warnings)
{
<tr>
<td>#Html.ValueFor(model => item.A)</td>
<td>#Html.EditorFor(model => item.B)</td>
<td>#Html.EditorFor(model => item.C)</td>
</tr>
}
</table>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
when I click Save, it posts to the action but only Id is assigned to the object, not myCollection.
What do I need to do to include the collection when posting them to controller?
Update
Model is generated by Entity Framework
public abstract partial class MyBaseClass
{
public Module()
{
this.MyCollection= new HashSet<Warning>();
}
public int Id { get; set; }
public virtual ICollection<Warning> MyCollection { get; set; }
}
public partial class MyClass : MyBaseClass
{
// more properties that aren't used on this controller
}

In order to get this to work you need to understand how ASP.NET MVC handles model binding for a List. Scott Hansleman has a good post explaining this.
Since your question was rather vague in terms of what the actual properties you're dealing with are, I put together a little example which successfully binds to a list:
Controller
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
//Initial test data
var zoo = new Zoo()
{
Id = 1,
Name = "Vilas Zoo",
Animals = new List<Animal>()
{
new Animal() {
Id = 1,
Name = "Red Panda"
},
new Animal() {
Id = 2,
Name = "Sloth"
},
new Animal() {
Id = 3,
Name = "Badger"
},
}
};
return View(zoo);
}
[HttpPost]
public JsonResult Index(Zoo zoo)
{
return Json(zoo);
}
}
Model
public class Zoo
{
public int Id { get; set; }
public string Name { get; set; }
public List<Animal> Animals { get; set; }
}
public class Animal
{
public int Id { get; set; }
public string Name { get; set; }
}
View
<h1>#Model.Id - #Model.Name</h1>
#using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
for (var i=0; i < Model.Animals.Count; i++)
{
#Html.EditorFor(m => Model.Animals[i])
}
<button type="submit">Save it, yo</button>
}
Notice how I'm using a for loop instead of a foreach and the actual index of the loop is being used in the call to EditorFor.
