dynamic list loading while typing

[daonsh]

How about a possibility to dynamically load list of options (from server) to autocomplete what user types?

E.g. for the stock market if user types MSF it will show list with MSFT (Microsoft), etc. (search on server side).

Current behavior:
At the moment I see that I can load the choices list dynamically (from server json) but only once, on-load.
Perhaps there's a trick/tweak that will allow me to reload list every time user types something (to filter results).
If there is, it will probably be useful to many people and merits to be included in the docs.
