[jQuery] [autocomplete] jQuery plugin of bassistance -> Howto enhance functionality?


Hello together,
I'm using the Autocomplete jQuery plugin from bassistance, see
http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/
It actually works fine. When I click on an element from the
autosuggest-list, it's value is correctly transfered to the associated
input field.
Now I want to enhance the functionality as the following. When I click
an element from the autosuggest-list, I want to trigger a PHP script,
which does a search over the passed value right away.
I unfortunately have no idea how to do that. Anyone have an idea?
Here my code:
<script src="../../include/jquery/jquery.js" type="text/javascript"></
script>
<link rel="stylesheet" href="../../include/jquery/autocomplete/
jquery.autocomplete.css" type="text/css" />
<script type="text/javascript" src="../../include/jquery/autocomplete/
jquery.autocomplete.js"></script>
<script>
    $(document).ready(function() {
            function selectItem(li) {
                    return false;
            }
            function formatItem(row) {
                    return row[0] + " <i>(" + row[1] + " Geräte)</i>";
            }
            $("#suggestion").autocomplete("../../include/
suggest_quicksearch.php", {
                delay:10,
                minChars:3,
                matchSubset:1,
                matchContains:1,
                width:250,
                selectFirst:false,
                onItemSelect:selectItem,
                formatItem:formatItem,
                cacheLength:10
            });
    });
</script>
Thanks for your help.
