@BerndB: Thanks it works perfectly and even is more extendable.

$('#loginlink').live('click',function(){
    DC = 'login_box';
    diaOpt = {
        autoOpen : true,
        width : 400,
        title : 'Login',
        buttons: {
            //valiudate login
            'Login' : {
                text : 'Login Now',
                id : 'validateForm',
                click : function(){
                }   
            }
        }
    }

    launchDialog(diaOpt, DC);
});

$('#validateForm').live('click', function(){
    alert('Hellop');
    $("#loginform").validate();
});
