Why submits from JotForm are not triggering a script on Google Spreadsheet?

Hello,

I have implemented Google Apps script triggers for all types there are (simple, installable), both with change/edit/form submit types. They work fine when I change the sheet.

However none of them work when JotForm submits a new row to the sheet.

Is this supposed to work? Or is the integration done in such a manner that the Google Apps Script triggers are not ever executed?

After some investigation regarding your issue and I am afraid that google triggers will not work when new submission come to the Google spreadsheet.
