How to persist check-box checked - MVC/JQuery

I'm using MVC framework and on my page i have few checkbox and based on the checkbox user checked i'm showing the div with input/buttons etc... but when the user post the page and if the page has any errors it refresh the entire page and my selection is gone and again i have to check the checkbox to show the div.

My question is how can I persist the selection? How do I update the selection in this case the selection is which checkbox is checked and update the property in the controller EmployeeChk

I have tried something like this:

.Model class

property bool EmployeeChk {get; set;}
property bool EmployerChk {get;set;}

//View page:

<table width="auto">
        <tr>
            <th>
                Employee
            </th>
            <td>
                @Html.CheckBox("Employee")
            </td>
        </tr> 
    </table>

<fieldset id="emp" style="@(Model.EmployeeChk ? "" : "display: none")" class="fieldset-auto-width">
<legend>
    <legend>
        Employee Display
    </legend>

    @using (Html.BeginForm("EmployeeServer", "EmployeeForm", FormMethod.Post))
    {
        @Html.ValidationSummary(true)

        <div>..... </div>

    }

</fieldset>

JQuery:

<script>
    $(document).ready(function() {

        $('#Employee').change(function() {
            if (this.checked) { 
                $('#emp').show();
            }  
        });
 });
</script>
