Database Triggers - Autonomous Transaction Issue

Question

Hi ,
I have a EMP table.
I wrote a AFTER ROWLEVEL Database Trigger for EMP table.
While Updating value in EMP table , my trigger is firing.
Issue:
My requirement is , I want to find the Count(1) in EMP table for the updated record.It is not including the updated record in my count.
If i execute the count(1) , outside the session , it is giving the correct value.But inside trigger i am not getting the exact count.
Can u pls help me.
Sample Coding:
While updating DEPT_CODE , the following trigger is firing.
CREATE OR REPLACE TRIGGER testing
AFTER UPDATE OF DEPT_CODE
ON EMP
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
t_count number;
cursor c_emp
is
select count(1)
from emp
where dept_code = :NEW.DEPT_CODE;
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
open c_emp;
fetch c_emp into t_count;
close c_emp;
dbms_output.put_line('t_count '||t_count);
END;
I got count as 5.
But if i execute the count in SQL , it is giving count as 4.
In the database trigger , it is not taking the record which was updated .
