how to inspect element _events in crm?

Hello - I'm trying to identify the events associated with a clickable element in CRM.  Here's a very condensed version of the element in question:

<a id="example" role="button" onclick="return false;" href="BLOCKED SCRIPT;" mscui:controltype="" _events="[object Object]">

This is a clickable button on the ribbon.  I think it's a custom button.  Based on the element above the _events attribute appears to be associated with some type of object - I'm guessing some type of function lookup.  So is there any way in the browser F12 view to inspect the _events object associated with this element?
