code: public JQMButton setRightButton(String text) {
          return setRightButton(text, (String) null, (DataIcon) null);
      }
docs: Creates a new {@link JQMButton} with the given text and then sets that
  button in the right slot. Any existing right button will be replaced.
  
  This button will not link to a page by default and therefore will only
  react if a click handler is registered. This is useful if you want the
  button to do something other than navigate.
  
  @param text
  the text for the button
  
  @return the created button
