Trouble with ITS

Hi , I am new to ITS server and I have a request where one button needs to be added to a screen . I have added this button at the back from screen painter and in the internet services , I have put the HTML code for this button with the right names. Do I have to simply save the code or is there a procedure to publish it , so that it shows on the browser. Right now I can not see it onthe browser.

Thank you .
