Answer 1

I think you are adding more and more listeners to 'result' each call you make to check.

First time click -> call 1 console.log from call 1 listener

Second time click -> call 1 console.log from call 1 listener + call 2 console.log from call 1 listener + call 2 console.log from call 2 listener

Third time -> The previous logs + call 3 console.log from call 1 listener + call 3 console.log from call 2 listener and call 3 console.log from call 3 listener.

Try putting the listener for 'result' out of the function:
