Answer 1

There isn't anything wrong with that particular buttons coding.  There may be something that makes that button different such that using   event.target  may not be appropriate.  Try using   event.currentTarget  and see if that improves anything.
Other than that, for the code you show, there is a misplaced " { " ... }function navigate.... it belongs at the end of the function.
