RowVersion value is not getting binded in form data, mvc 5 - asp.net-mvc

Question

I am trying to implement concurrency using EF6 in MVC 5.
#Html.HiddenFor(model => model.RowVersion)
On my edit page I am able to see the rowversion value in input type hidden.
<input id="RowVersion" name="RowVersion" type="hidden" value="AAAAAAAAF3M=">
But on $('form').serializeArray() I am not getting RowVersion data, on posting the form also I am getting null value of RowVersion property.
I had added RowVersion column in database table later and updated the edmx after that, I have set concurrency mode to fixed in the primary key column property my table in edmx.
Is there something extra that needs to be done for rowversion ?
Any help would be appreciated.
Update : adding html code
Jquery : I am checking it in console using : $('form').serializeArray()
html output from browser :
<form action="/Master/EditBookMaster/13" method="post"><input name="__RequestVerificationToken" type="hidden" value="Y04ae_LHgfG9Tw9hy2TcHIYbxk_EX_vykyphV7Sm9Wwiz6_f8PpGUY2SULyiZbCdJv4fgBloOlx_QRUz1FQNvXTZUorLt6_EvA9XLxcFsxbQqUlmY9XOCduHa__q1kdRQJpFAx4wOuj5tRu48TLh9A2" /> <div class="form-horizontal">

Answer 1

$(":input,:hidden").serialize();
code instead of
$('form').serializeArray()
