Apply luci page save for every 10s automatically

Hi, currently I am displaying /etc/file.conf contents in the luci webpage (at luci/admin/services/file) in text box using text value in cbi/file.lua file. what I need to do is when something is changed in /etc/file.conf it should update automatically on the luci webpage. or webpage should refresh for every 10s. How can I achieve this ??
