Jak poradzić sobie ze zmianą checkboxa za pomocą jQuery?

Mam jakiś kod 

<input type="checkbox" id="chk" value="value" />
<label for="chk">Value </label>
<br/>
<input type="button" id="But1" value="set value" />
<br />
<input type="button" id="But2" value="read checked" />

Javascript: 

$(document).ready(function () {
    console.log("Ready ...");
    registerHandlers();

    function registerHandlers() {
        $('#But1').click(function () {
            $('#chk').prop('checked', !$('#chk').is(':checked'));
        });
        $('#But2').click(function () {
            var chk1 = $('#chk').is(':checked');
            console.log("Value : " + chk1);
        });

        $('input[type="checkbox"]').change(function () {
            var name = $(this).val();
            var check = $(this).prop('checked');
            console.log("Change: " + name + " to " + check);
        });
    }
});

Jak poradzić sobie ze zmianą checkboxa za pomocą jQuery ? Muszę umieścić obsługę, aby zmienić zaznaczone pola wyboru.

[update]

Jest pole wyboru i kilka przycisków. Każdy przycisk może zmienić pole wyboru. Jak złapać Zdarzenie zmieniające pole wyboru?

[Update]

I need handle change checkbox in this example jsfiddle. Po kliknięciu na pole przycisk "OK" nie jest pokazane.

Użycie :checkbox selektor: 

$(':checkbox').change(function() {

        // do stuff here. It will fire on any checkbox change

});

Możesz również użyć Id pola 

$('#checkbox1').change(function() {
   if($(this).is(":checked")) {
      //'checked' event code
      return;
   }
   //'unchecked' event code
});

Hope, to byłoby pomocne.

$('input[type=checkbox]').change(function () {
    if ($(this).prop("checked")) {
        //do the stuff that you would do when 'checked'

        return;
    }
    //Here do the stuff you want to do when 'unchecked'
});

$("input[type=checkbox]").on("change", function() { 

    if (this.checked) {

      //do your stuff

     }
});

Wydaje mi się, że removeProp nie działa poprawnie w Chrome : jsfiddle 

        $('#badBut1').click(function () {
        checkit('Before');
        if( $('#chk').prop('checked') )
        {
          $('#chk').removeProp('checked');
        }else{
            $('#chk').prop('checked', true);
        }
        checkit('After');
    });
    $('#But1').click(function () {
        checkit('Before');
        if( $('#chk').prop('checked') )
        {
          $('#chk').removeClass('checked').prop('checked',false);
        }else{
            $('#chk').addClass('checked').prop('checked', true);
        }
        checkit('After');
    });

    $('#But2').click(function () {
        var chk1 = $('#chk').is(':checked');
        console.log("Value : " + chk1);
    });

    $('#chk').on( 'change',function () {
        checkit('Result');
    });
    function checkit(moment) {
        var chk1 = $('#chk').is(':checked');
        console.log(moment+", value = " + chk1);
    };

Get radio value by name 

  $('input').on('className', function(event){
        console.log($(this).attr('name'));
        if($(this).attr('name') == "worker")
            {
                resetAll();                 
            }
    });
