[jQuery] autocomplete question

[Bjarki]

I am looking at the auto-complete demo page, (
http://view.jquery.com/trunk/plugins/autocomplete/demo/ ) on the demo
of remote images.
the Javascript for that is
$("#imageSearch").autocomplete("images.php", {
                width: 320,
                max: 4,
                highlight: false,
                scroll: true,
                scrollHeight: 300,
                formatItem: function(data, i, n, value) {
                        return "<img src='images/" + value + "'/> " + 
value.split(".")[0];
                },
                formatResult: function(data, value) {
                        return value.split(".")[0];
                }
        });

my problem is that when I try to implement this. it will only search
for the data that is first in the string. so if  I have a "<span>" +
data.N "</span>  I have to type in <span> to see any results, how to I
configure this to just match the data.N ?

function getEmpSuccess(data){
        eval("empColl = " + data + ";");
        $("input[id$='query']").autocomplete(empColl["E"], {
                                        formatItem: function(data) {

                                                var rts = data.N;
                                                rts +='<div class="color' + 
data.W + '">&nbsp;</div><br />';
                                                rts += "<sub>" + data.S + 
"</sub>";

                                                return rts;
                                        },
                                        formatResult: function(item, value) {
                                                return item.N;
                                        },
                                        selectFirst: false,
                                        max: 5
                                });
}
