MVC Form Serialize Passing List<ViewModel> to Ajax Post seems to not be working?

Hello all,

I have a MVC view that I use an Ajax post which is working great with a Form.Serialize but one of the properties in the view model is a list such as List<MyViewModel>  entries.    When I make a call to the controller create a new List<MyViewModel> pass it to the view its there but on the Ajax Post it seems to either be null or 0 for the count.   Any idea why that would happen, should it not be passed like the other string view model get; set; properties etc?

Thanks all

Here is the Ajax post:
$(document).on('click', '.addDataEntry', function () {

                var $form = $("#portfolioMVForm");
                var serializedData = $form.serialize();
                var url = '@Url.Action("AddPortfolioMarketValueEntry", "Portfolio")';

            $.ajax({
                type: "POST",
                url: url,
                data: serializedData,
                dataType: 'json',
                success: function (data) {
                    $('#PortfolioMVEntryContent').html(data.PartialView);
                },
            });
        }

Use the F12 Developer Tools Network capture to view the POSTed data and the content response and verify they data is ok. Also, you can put a breakpoint on line 13 to view the data object is as expected.
