How to handle change of checkbox using jQuery?

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);
});
}
});

I need to put the handler to change any checkboxes checked.

[update]

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

I need handle change checkbox in this example jsfiddle.
When I click on the box the message "OK" button is not shown.

Answer

Use :checkbox selector:

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

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

});
