asp.net-mvc-3 - Form collection is not retrieving the form input values from a replace div

Question

I am binding a model to a view in ASP.NET MVC. The model is a collection object. At my first submit I am getting the input values in my form collection.

After the form submit, I replacing the div in the from with a partial view

$.post("/formDetails/CheckValid", $('#Form').serializeArray(), function (htmlResult) 
{
    $('#divtoReplace').html('');
    $('#divtoReplace').html(htmlResult);
}

But after replacing the div, I am unable to get the input values from the replaced div through the jQuery submit.

Please help me on sorting this issue.
