How to properly distribute rights for samba?

Question

linux

Hello.
There is an OS with the samba service installed
Version:
Linux version 3.10.0-327.3.1.el7.x86_64
NAME="Red Hat Enterprise Linux Server"
VERSION="7.2 (Maipo)"
ID_LIKE="fedora"
VERSION_ID="7.2"
PRETTY_NAME= Red Hat Enterprise Linux Server 7.2 ( Maipo
) ="7.2" smbclient -V Version 4.2.
pdbedit -a -u usersamba
and issued the rights (I understand that apparently this is not possible, BUT I wanted to achieve the result faster)
sudo chmod –R 777 /data
Config

; /etc/smb.conf
;
; /etc/rc.d/init.d/smb stop
; /etc/rc.d/init.d/smb start

[global]
 guest account = usersamba
   log file = /var/log/samba-log.%m
   lock directory = /var/lock/samba
   share modes = yes

[data]
   comment = files source
   path = /data
   read only = no
   public = yes
valid users = usersamba
create mode = 0750
        writable =  yes
        guest ok = Yes
browseable = yes

The connection is successful.
I see files.
I transfer successfully.
BUT when new files appear in the folder, their transfer for the usersamba user is no longer possible.
Please help me solve the problem.
