Javascript easyautocomplete TypeError

Question

我试图运行http://easyautocomplete.com/example/select-event
但每当我填写inputOne时，它返回错误：

Uncaught TypeError: $(...).getSelectedItemIndex is not a function
    at Object.onSelectItemEvent (data.js:6)
    at HTMLDivElement.<anonymous> (jquery.easy-autocomplete.min.js:10)
getSelectedItemData()    at HTMLDivElement.dispatch (jquery-1.11.2.min.js:3)

代码（html）：

<input id="inputOne" placeholder="X-men character" />
<input id="inputTwo" placeholder="Real name" />

<script>
var options = {

    data: [
        {"character": "Cyclops", "realName": "Scott Summers"},
        {"character": "Professor X", "realName": "Charles Francis Xavier"},
        {"character": "Mystique", "realName": "Raven Darkholme"},
        {"character": "Magneto", "realName": "Max Eisenhardt"},
        {"character": "Storm", "realName": "Ororo Monroe"},
        {"character": "Wolverine", "realName": "James Howlett"}
    ],

    getValue: function(element) {
        return element.character;
    },

    list: {
        onSelectItemEvent: function() {
            var selectedItemValue = $("#inputOne").getSelectedItemData().realName;

            $("#inputTwo").val(selectedItemValue).trigger("change");
        },
        onHideListEvent: function() {
            $("#inputTwo").val("").trigger("change");
        }
    }
};

$("#inputOne").easyAutocomplete(options);
</script>

我正在运行python flask来提供文件。让我知道你的想法。
