Title: changed attr('data-target') to data('target');

this will extend js interface, to be possible to setup targets for tabs that setted like

var content=$('

',{text: 'content'});
var tab=('
',{html: $('',{text: 'Main options'})}).addClass('active').data({target: $main,toggle: 'tab'}).appendTo(tabs);

or just selected to js variable.
