Extending btn-group / btn-group-toggle

[laventnc]

I'm trying to wrap/extend the core functionality of the checkbox/radio button plugin, and I can't seem to find any documentation on how to do so. My goal is to add the class 'disabled' to the container button when the input inside is disabled.

While other components (like dropdown / modal) expose some events, there are no events listed for the this functionality. My idea was to wrap/extend this component, however I haven't located any info on how to do so. I've looked in both the Extend and Javascript overview pages for info, as well some searches within the project & stack overflow. I also looked at the source code, and couldn't find the relevant code.

Is there a way to extend core functionality in the absence of exposed events? Any info on this topic would be helpful, thank you!
