Records Not Being Updated in Stored Procedures

Hello - I have a stored procedure which inserts records into a database. I have found that, when executing the SP, the database does not show the changes until i reinitialize the procedure (or replace it). ie. ill run the procedure, but do not see that a new record was added to the database until i actually define the procedure again using the "create or replace" function below. is there something i am missing in my definition of the procedure or the way i call it? thanks

create procedure BYO_INSERT_CUSTOMER (temail IN varchar2) AS
BEGIN
        insert into Isuzu2k_Users_Personal(email) values (temail); END;
