How can I update the Database on a checkbox change in MVC

I am trying to update my database when a checkbox is checked or unchecked. I want it to update when the checkbox is clicked. This is what I have so far, but my controller is never being hit. what can I do to fix it? Ideally I want to pass in the new value of customer.IsDone and customer.Id to my controller but I don't know how to do this.

Checkbox in my view

    <td>@Html.CheckBoxFor(m => customer.IsDone, new { onclick = "UpdateCustomer(IsDone)" })</td>

The function in my view

function UpdateCustomer(isDone) {
        $.ajax({
            type: 'POST',
            url: @Url.Action("UpdateCustomer", "Home"),
            data: { check: isDone },
            success: success,
            dataType: 'json'
        });
    }

this is my controller method

    [HttpPost]
    public ActionResult UpdateCustomer(bool check)
    {
        //code will be here to update the db

        var customers = new CustomerGetAll();
        var list = customers.Execute();

        return View("Customers", list);
    }
