or
I've figured out how to initialize a ButonGroup with badges using this documentation:
items - API Reference - Kendo UI ButtonGroup - Kendo UI for jQuery (telerik.com)
Now I want to update badge options or remove a badge after initialization. I found this documentation:
badge - API Reference - Kendo UI ButtonGroup - Kendo UI for jQuery (telerik.com)
However, this only seems to allow updating the text value of the badge. I want to be able to update other things like themeColor. Furthermore, if a badge is removed by calling:
buttonGroup.badge(index, false);
