JQuery UI Autocomplete - How to select an item and mantain the label (not the value) in the input text

I´m trying to use the JQuery UI Autocomplete plugin (click to see the demo page of JQuery UI Autocomplete plugin)

I´m using as datasource a list of objects as bellow:

            var availableTags = [
                 {label: "Sao Paulo", value: "SP"},
                 {label: "Sorocaba", value: "SO"},
                 {label: "Paulinia", value: "PA"},
                 {label: "São Roque", value: "SR"}
            ];

The problem is that when I select an item, the value of the datasource is set to the input field and not the label. I´ve created a handle to the select to save the item value in a hidden field and set the label to the input field, but this event is fired too soon by the plugin and the value is re-set to the input field.

                     {label: "São Roque", value: "SR"}
                ];   

                $("#txtCidade").autocomplete({ minLength: 0,
                                               source: availableTags);     
            });

            function OnSelect(event, ui)
            {
                var item = ui.item;
                var itemLabel = item.label;
                var itemValue = item.value;

                $("#hidCidade").val(itemValue);
                $("#txtCidade").val(itemLabel);
            }

        </script>
    </head>
    <body>
        <form>
            <input id="hidCidade" type="hidden" />
            <input id="txtCidade" type="input" class="ui-autocomplete-input" />
        </form>
    </body>
</html>

Please, could someone help me with this?

Thanks!

Since I just had to solve this too. I thought I would show my solution. IMHO it is cleaner since you don't need the separate OnSelect and OnFocus functions. (though it really does the same thing as what rperson ended up doing)

$('#txtCidade').autocomplete({
  source: availableTags,
  focus: function(event, ui) {
    $(this).val(ui.item.label);
    return false;
  },
  select: function(event, ui) {
    $('#hidCidade').val(ui.item.value);
    $(this).val(ui.item.label);
    return false;
  }
});

Change your autocomplete call to the following:

$("#txtCidade").autocomplete({
    source: availableTags,
    select: function(event, ui) {
         $("#hidCidade").val(ui.item.label);
    }
});

#txtCidade should automatically pckup the selected label when an autocomplete item is clicked on.

See a jsFiddle example here.

I´ve solved the issue creating the handlers for OnFocus and OnSelect and returning false in each one.

        function OnFocus(event, ui)
        {
            $( "#txtCidade" ).val( ui.item.label );
            return false;
        }

        function OnSelect(event, ui)
        {
            var item = ui.item;
            var itemLabel = item.label;
            var itemValue = item.value;
            var campo = $("#txtCidade");

            $("#hidCidade").val(itemValue);
            $("#txtCidade").val(itemLabel);

            var campoValue = campo.val();
            var hidCampoValue = $("hidCidade").val();
            return false;
        }
