If you want to uncheck the checkbox which was just check, then:

$(obj).attr("checked", false);

If another one:

$("#checkboxid").attr("checked", false);

If all of them:

$("input:checkbox").attr("checked", false);

You can call a function onchange and uncheck the desired checkbox

$("#chkbox_id:checked").attr("checked", false);
