 * Are you putting this in your functions.php file? If you just include the add_action(‘
   init’,’newposttype_create’) with the function newposttype_create(), do you see
   the “mysliderservice” in the wordpress admin? If so, then your register post 
   type is working and it’s a problem with the form.

 * user go to wp-admin plugin page and then put some in the form and then it will
   create a custom post type with this name.

 * Ah I see. I’m not really sure what to suggest except have you activated your 
   custom plugin to see the post type shows in the admin bar?

   I implemented it at my end and it is working fine.
