Dynamically Reload UI Macro on Incident Form

Hi Guys,

Hypothetical:

I have an incident form with a UI Formatter that represents a macro that shows 10 related knowledge articles below the short description field.
Is it possible to dynamically show a new set of results on the form into the macro without reloading the page?

It seems to have been done here (http://v-savitsky.narod.ru/dynamic_kb_search.png), where a client script appears to feed results of a query into a UI Formatter directly. How can this be achieved?

Thanks
