Module development and code questions

Is it possible to capture IDs of clicked-on inputs using logic from a behaviors file when the inputs are used in AJAX?

At a high level, I'd like to capture the IDs of elements when they're clicked-on. It looks like I can do it individually when using a mousedown handler with the respective IDs, but I want it to be more abstract in the sense of having a dynamic way of not needing to reference the ID in the code if possible.

Thanks!
