How to get the value of checkboxes in to the controller method in asp.net MVC

I am generating my Checkboxes from an IEnumerable model class like below.

<table class="table table-bordered">

    <thead> 
    <tr>
        <th>@Html.DisplayName("Id")</th>
        <th>@Html.DisplayName("FirstName")</th>
         <th>@Html.DisplayName("LastName")</th>
         <th>@Html.DisplayName("Username")</th>
        <th>@Html.DisplayName("Organization")</th>
        <th>@Html.DisplayName("Active")</th>
        <th>@Html.DisplayName("Block")</th>
         <th>@Html.DisplayName("Action")</th>
    </tr></thead>
    @foreach (var item in Model.Employer) {
    <tr>
        <td>@Html.DisplayFor(modelItem=>item.Id)</td>
        <td>@Html.DisplayFor(modelItem=>item.FirstName)</td>
         <td>@Html.DisplayFor(modelItem=>item.LastName)</td>
         <td>@Html.DisplayFor(modelItem=>item.Username)</td>
         <td>@Html.DisplayFor(modelItem=>item.Organization)</td>
         <td>@Html.CheckBoxFor(modelItem=>item.Active)</td>
         <td>@Html.CheckBoxFor(modelItem=>item.Block)</td>



        <td>
            @using (Html.BeginForm("DeleteEmployer", "Admin"))
             {
                @Html.Hidden("employerId", item.Id)
                  <input type="submit" value="Delete"/>
            }


        </td>
        <td>

             @using (Html.BeginForm("UpdateEmployer", "Admin"))
             {
                @Html.Hidden("eId",item.Id)
                     @Html.Hidden("Active",item.Active)
                      @Html.Hidden("Block",item.Block)
                  <input type="submit" value="Update"/>
            }

        </td>
    </tr>
    }
</table>

I am attempting to get my ID and the values of the active and block checkboxes selections for a particular row on my Update button click. My id passed correctly. However, active and block selections are not changing. I Understand that my Active and Block being columns from my DB cannot be used for editing or strong-typing here. I thought of adding new columns to my model "SelectionActive" and "SelectionBlock" to my Employer model. However this results in so many error in my project for i used the model in many places and the two columns are not from a Db. Please how do i get the value of my Selections to my controller below.

public ActionResult UpdateEmployer(long Id, bool Active ,bool Block)
        {

            if (ModelState.IsValid)
            {
                repository.UpdateEmployer(Id,Active,Block);
                TempData["Employermessage"] = string.Format("{0} was updated", Id);
            }
            return RedirectToAction("Index");
        }

Any help would be appreciated.
