How to handle change of checkbox using jQuery?

Question

I have some code

<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);
        });
    }
});

There is a checkbox and a few buttons. Each button can change check box. How to catch an event changing the checkbox?

Use :checkbox selector:

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

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

});
