Thanks

$(function() {
    $("#radio").buttonset();
    $("#disable").click(function(e){
        e.preventDefault();
        $("#radio").buttonset( "option", "disabled", true );
    });
    $("#enable").click(function(e){
        e.preventDefault();
        $("#radio").buttonset( "option", "disabled", false);
    });
});
