Why don't you use Ajax.BeginForm() this makes so easy to send posted form value.

Also, you should create proper model first.

MODEL

    public class UserRole
    {
    public Administrator Administrator { get; set; }
    public FreeUser FreeUser { get; set; }
    }
    public class Administrator
    {
    public int Checkbox1 { get; set; }
    }
    public class FreeUser
    {
    public int Checkbox1 { get; set; }
    }

Do following in View.

    @model Model.UserRole
    <div id="result"></div>
    @using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "result" }))
    {
        <input type="hidden" name="RoleID" value="1" id="RoleID" />
        <table id="mytable">
            <tr>
                <td>View</td>
                <td>Insert</td>
                <td>Update</td>
                <td>Delete</td>
            </tr>
            <tr>
                <td>Administrator</td>
                <td>
                    @Html.CheckBoxFor(m => m.Administrator.Checkbox1)
                </td>
            </tr>
            <tr>
                <td>Free User</td>
                <td>
                    @Html.CheckBoxFor(m => m.FreeUser.Checkbox1)
                </td>
            </tr>
        </table>
        <br />
        <button type="submit" class="buttons buttons-style-1" onclick="Save()">Save</button>
    }

Controller action

    [HttpPost]
    public ActionResult Index(UserRole model)
    {
        return View();
    }

Also don't forget to include ajax library.

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
