Want update a date field based on most recent email date

I want to automatically update a date field in a Contact when a new email is attached to that Contact. This is a field created for the Contact layout called "Last Outgoing Contact". I created a function to do this, but it doesn't appear to work.

  2. //access the emails field from the Contact
  3. emailInfo = zoho.crm.getRelatedRecords("Contacts","ID","Emails","Emails");
  4. //create a list of every email from that Contact
  5. emailList = emailInfo.get("Emails");
  6. //count the number of emails in that list
  7. count = emailList.size();
  8. //if the number of the emails in the list is greater than 0, get the most recent email's Created Time date
  9. if(count > 0)
  10. {
  11. mostRecentDate = emailList.get(0).get("Created Time");
  12. for each index i in emailList
  13. {
  14. if(emailList.get(i).get("Created Time") > mostRecentDate)
  15. {
  16. mostRecentDate = emailList.get(i).get("Created Time");
  17. }
  18. }
  19. // Update the Last Contact Date with that date
  20. put("Latest Outgoing Contact",mostRecentDate);
  21. }
  22. return;
