Hi Marco,
During the initialization process, we modify the DOM by adding new elements, removing elements, styling them, etc. It’s like a template which we process to make the component. In this scenario, after the component is initialized you can set its ‘title’ attribute.
You can set it after the initialization of the Button Group UI Component:
$("#bg").jqxButtonGroup({ mode: 'radio', enableHover: true});
$("#b1").jqxButton({});
$("#bg").children()[0].title = "test";
