#1, #2
You see the internals of CanJS, because technically that is the handler for the event. A breakpoint inside that function will point you towards the actual method in the Control that is called.
#4
Doesn't surprise me since this tool doesn't seem to be in active development
#3
All FireQuery is showing you is the data on the element. When a Control is created, the instance is added to the data Object of the element. So you can see the methods, options, prototype of the instance, but it does not show events. There is a _bindings property, but it is not useful for what you are looking for. You see a 'click' function because that is the name of that method in the Control. You can see the same thing in your source code.

You will get the same result as #1 and #2 when his change lands in Chrome.
