DELETE from another table with trigger/trigger function

Question

Trying to use trigger to delete a row from a table when a column with the same value is delete from the original table

    CREATE OR REPLACE FUNCTION testFunc()
  RETURNS trigger AS  
$func$
BEGIN  
   DELETE FROM emergencyinfo
   USING  massacts
   WHERE  emergencyinfo.actid = massacts.id;

RETURN NEW;

END
$func$  LANGUAGE plpgsql;

Trigger;

CREATE TRIGGER test_trigger3 
AFTER DELETE ON massacts 
FOR EACH ROW EXECUTE PROCEDURE testFunc();

This does not work, when i execute query 'delete from massacts where id=5', the row deletes from massacts but the row that holds actid=5 in emergencyinfo does not delete.

However, when i try this trigger by updating a row's id to 5 in massacts table, the row in emergencyinfo with actid=5 does delete.

CREATE TRIGGER test_trigger3 
AFTER UPDATE ON massacts 
FOR EACH ROW EXECUTE PROCEDURE testFunc();

I have tried to use BEFORE DELETE instead of AFTER, same issue persisted.
