unbind click event for last list element

Question

Hi all,

I was trying to customize the jQuery autocomplete plugin... I have to add a turn off button at the end of the result set returned. The problem is that I have added a button to the returned result set but when I click on the button the HTML of the button goes into the text box.... I hope I am making some sense... From what I understand I have to unbind the event for that ... I did some trial and error but no success :-( e.g.

for (var i=0; i < max; i++) {
    if (!data[i])
        continue;
    var formatted = options.formatItem(data[i].data, i+1, max, data[i].value, term);
    if ( formatted === false )
        continue;
    var li = $("<li/>")
        .html( options.highlight(formatted, term) )
        .addClass(i%2 == 0 ? "ac_even" : "ac_odd").appendTo(list)[0];
    if (i == max-1 || i == max-2) {
        ***$li.unbind('click');***
    }

The plugin stops working.....

Second experiment

list = $("<ul/>").appendTo(element).mouseover( function(event) {
    if(target(event).nodeName && target(event).nodeName.toUpperCase() == 'LI') {
        if (noResFlag != -1) {  
            active = $("li", list)
                .removeClass(CLASSES.ACTIVE)
                .index(target(event));
            $(target(event)).addClass(CLASSES.ACTIVE);
        }
    }
}).click(function(event) {
    if (noResFlag != -1) {
        $(target(event)).addClass(CLASSES.ACTIVE);
        select();
        // TODO provide option to avoid setting focus again after selection?
        // useful for cleanup-on-focus
        input.focus();
    }
    return false;
}).mousedown(function() {
    config.mouseDownOnSelect = true;
}).mouseup(function() {
    config.mouseDownOnSelect = false;
}).mouseout(function(event){
    $("li", list).removeClass(CLASSES.ACTIVE).index(target(event));
    return false;
});

var i1=$('li',list).size() ;
alert(i1);
$("li", list).each(function (i) {
    if ((i == i1 -1) || (i == i1-2)) {
        this.unbind('click');
    }
});

if( options.width > 0 )
    element.css("width", options.width);
needsInit = false;

here i1 always becomes zero...... :-(

thanks in advance... cheers abhi
