AFTER INSERT OR UPDATE TRIGGER the insert not working

Question

The update works but the insert is not working. I have two version that I have tried. I amd executing the inserts/update from Oracle Applications and the table row is either being inserted or updated correctly.
DROP TRIGGER APPS.CCC_HZ_ORG_CONTACTS_ARU;
CREATE OR REPLACE TRIGGER APPS.CCC_HZ_ORG_CONTACTS_ARU
/* --Created By: SKELLEHER
--Creation Date: 07/15/09
--Last Updated By:
--Last Update Date:  
AFTER INSERT OR UPDATE OF department, job_title
ON apps.hz_org_contacts
FOR EACH ROW
WHEN (
NEW.department <> OLD.department OR
NEW.job_title <> OLD.job_title
DECLARE
v_ChangeType VARCHAR2(10);
BEGIN
/* Use 'I' for Insert, 'U'' for Update, and'D' for delete(not part of app at this time). */
IF INSERTING THEN
v_ChangeType := 'INSERT';
ELSIF UPDATING THEN
v_ChangeType := 'UPDATE';
ELSE
v_ChangeType := 'DELETE';
END IF;
INSERT INTO cust.ccc_tca_po_tf_event_tbl
VALUES (ccc_tca_po_tf_event_tbl_s.NEXTVAL
, 'hz_org_contacts'
, v_ChangeType
, 'org_contact_id'
, :NEW.org_contact_id
, 'PENDING'
, NULL
, 0
, 'N'
, 'Y'
, :NEW.LAST_UPDATED_BY
, :NEW.LAST_UPDATE_DATE
, -1
, SYSDATE
, 'DEPARTMENT_JOBTITLE_UPDATE'
,'LDAP'
END;
AND I TRIED ANOTHER VERSION:

Answer 1

I have simplified it so it's just checking for insert but it's not picking up. Is the syntax IF INSERTING correct?
CREATE OR REPLACE TRIGGER APPS.CCC_HZ_ORG_CONTACTS_ARU
AFTER INSERT OR UPDATE
ON ar.hz_org_contacts
FOR EACH ROW
DECLARE
BEGIN
IF INSERTING THEN
INSERT INTO cust.ccc_tca_po_tf_event_tbl
VALUES (ccc_tca_po_tf_event_tbl_s.NEXTVAL
, 'hz_org_contacts'
, 'UPDATE'
, 'org_contact_id'
, :NEW.org_contact_id
, 'PENDING'
, NULL
, 0
, 'N'
, 'Y'
, :NEW.LAST_UPDATED_BY
, :NEW.LAST_UPDATE_DATE
, -1
, SYSDATE
, 'DEPARTMENT_JOBTITLE_UPDATE'
,'LDAP'
END IF;
END;
