ASP.NET MVC checkbox JQuery toggle only work once

I created a ASP.NET MVC project using VS2013, and created a model peron as shown below:

Then copy the following code to replace the view home index.cshmtl file. When I run it, the toggle worked once when I check the checkbox, the hide worked, but when I unchecked, it would not show. Anyone please help? I checked around and see similar issue but no real answers.

Person.cs as shown below:

using System;
using System.Linq;
namespace checkbox.Models
{
    public class Person
    {
        public bool IsActive { get; set; }
        public string Email { get; set; }
    }
  }

Below is the code for index page index.cshtml:

@model checkbox.Models.Person
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/jqueryval")


@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Person</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div id="myCheckbox" class="form-group">
            @Html.LabelFor(model => model.IsActive, htmlAttributes: 
            new {     @class = "control-label col-md-2" })
            <div class="col-md-10">
                <div class="checkbox">
                    @Html.EditorFor(model => model.IsActive)
                    @Html.ValidationMessageFor(model => model.IsActive, "", 
                    new { @class = "text-danger" })
                </div>
            </div>
        </div>

        <div id="ShowHideMe" class="form-group">
            @Html.LabelFor(model => model.Email, htmlAttributes: 
              new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Email, 
                  new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Email, "",
                  new { @class = "text-danger" })
            </div>
        </div>

         <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Save" class="btn btn-default" />
            </div>
        </div>
    </div>
}
<script type="text/javascript">
  $(function() {
      $('#myCheckbox').change(function() {
          $('#ShowHideMe').toggle($(this).is(':checked'));
      });
  });
</script>
