simple code problem in functions.php

Thanks Tara, here I hope is the fixed post:

Hi
in the functions.php
If I write this line of code, than it works and I get no admin bar for simple users:

if (get_current_user_id() != '1') {
add_filter('show_admin_bar', '__return_false');
}

But if I put the line above in a function like this, nothing happens:

// Remove admin items
function optimize_editor() {
if (get_current_user_id() != '1') {
add_filter('show_admin_bar', '__return_false');
}
add_action('admin_menu','optimize_editor');

I double checked (by using an echo) and the code inside the function is being called and the current user id is ‘2’.

– using
show_admin_bar(false);
yields the same results..

Thanks for any help!
