displaySubmissionResult() function only displays once

[JBourton]

Bug found when calling displaySubmissionResult() to display a success or error message to a user after a post request.

The function does it's job perfectly on the first comment submission, but on consecutive comment submissions it does not run.

This could maybe be fixed by changing the event listener for the form submit to an event listener for a button

This did not work.
