Oracle trigger inserting PK value, date and trigger value into second table when update/insert/delete

Oracle 11.2 - The goal is to create a trigger on table and anytime an update, delete or insert is done on the table, write values to a second table.  I have the trigger and it works except it is not loading my col1/PK values.  I cannot figure out exactly what I need to do and why this is not working or maybe a better/easier way to do this?  Any direction appreciated.  Col1 is my PK on Table that I  want to load anytime there is an update/delete/insert on the table.
My code:
CREATE OR REPLACE TRIGGER TRIGGER_NAME
AFTER INSERT OR UPDATE OR DELETE
    ON TABLE_NAME
    FOR EACH ROW
DECLARE
  v_col1 TABLE_NAME.COLUMN%type;
BEGIN
IF INSERTING THEN
    INSERT INTO NEW_TABLE
     ( col1,
       triggerdate,
       type)
    VALUES
     ( v_col1,
       sysdate,
       'I');
END IF;
IF UPDATING THEN
    INSERT INTO NEW_TABLE
     ( col1,
       triggerdate,
       type)
    VALUES
     ( v_col1,
       sysdate,
       'U');
END IF;
IF DELETING THEN
    INSERT INTO NEW_TABLE
     ( col1,
       triggerdate,
       type)
    VALUES
     ( v_col1,
       sysdate,
       'D');
END IF;
END;
