Integration between autocomplete and ajax.form plugin

Integration between autocomplete and ajax.form plugin

Hi to everyone, i'm programming with jquery and google maps and I have the following problem:

Into this page
http://www.federicarizzi.com/map/incomplete.html

i've create a text field where you can write a text to search a marker.

The autocomplete function works, but only if you select an item from the list and, after this, you press enter another time.

I wanna something like that: the user starts to write a code, then, when it select the item from the list, the search of the marker will start.

I hope you understand my problem.
sorry for my english!
