create dynamic table in store procedure without using any paramaters

CREATE OR REPLACE procedure create_table_dateWise21()
LANGUAGE plpgsql
as $$
BEGIN
EXECUTE format('
   CREATE TABLE IF NOT EXISTS test21 (
    nodeip text,
    interface text, 
    nodeip_interface text
   )');
commit;
end;
$$; 

if we ‘call create_table_dateWise21()’. It create only test21 table but i want every time new table with the same columns
