If checkbox is checked then enable EditorFor

I would like my Checkbox to disable EditorsFor if it is unchecked and enable them if it is checked. I know I have to use JavaScript, I found some codes in net, but it seems that they don't work.

Here is my View code:

@{Html.RenderPartial("_PartialError");}
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()

(...)

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

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

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

    (...)
}

And I wrote something like this and put in js file (ofc at the end of this code is ), but it doesn't work...

    $(document).ready(function ()
{
    $("#Czy_zuzywalny").click(function ()
    {
        if ($("#Ilosc_minimalna").attr("disabled") == "")
        {
            $("#Ilosc_minimalna").attr("disabled", "disabled");
            $("#Ilosc_optymalna").attr("disabled", "disabled");
            $("#Ilosc_minimalna").attr("value", "0");
            $("#Ilosc_optymalna").attr("value", "0");
        }
        else
        {
            $("#Ilosc_minimalna").attr("disabled", "");
            $("#Ilosc_optymalna").attr("disabled", "");
        }
    });
});

Nothing happens even if I check or uncheck my checkbox. Can anyone help me with that?
