transectsModal not refreshing tableview when saving and closing

[NickGulajec]

The view behind the modal should refresh with the database changes on modal "save and close". A fireEvent/eventListener should do the trick. However...
At the moment an alert is set to trigger when this event fires. This alert will fire more than once on subsequent edits to a transect, when it should only always fire once.
Understanding and preventing this should make "tableView behind modal refresh automatically" possible.

More detail: the alert only fires more than once when going back a screen and re-entering the transects screen. So it must be that when using the top-left button to go back to a previous screen, the current screen is not actually closed, but put in a suspended state. Navigating forward to that view again opens another copy of it. Seems prone to memory misuse.

Moved the code that populated the tableView into a function. When closing the modal view, fired a global event that calls the populateTable function. This solved the issue with the table not updating.
