$(…).autocomplete(…).data(…) is undefined JS error

I get three JS errors in my JS console from script.js, lines 799, 1002 and 838

$(…).autocomplete(…).data(…) is undefined JS error

I believe it has to do with this code.

The odd thing is, my instagram feed is working fine, however another module on my site that uses JS is not working, and I think it’s related to this JS error.

$.ajax({
        url: ajaxurl,
        dataType: 'json',
        cache: false,
        data: {'action': 'get_stream_names'},
        success: function (data) {
            if (data) {
                $('#stream_name').autocomplete({
                    search: function (event, ui) {
                        $(this).removeClass("wait");
                    },
                    responce: function (event, ui) {
                        $(this).removeClass("wait");
                    },
                    source: function (request, response) {
                        var matches = $.map(data, function (tag) {
                            if (tag.toUpperCase().indexOf(request.term.toUpperCase()) === 0) {
                                return tag;
                            }
                        });
                        response(matches);
                    },
//                    minLength: 1,
                    select: function (event, ui) {
//                        alert(ui.item.value);
                        var val = ui.item.value;
                        document.getElementById("streamcount").innerHTML = val.length;
                    }
                }).data("ui-autocomplete")._renderItem = function (ul, item) {
                    var newText = String(item.value).replace(
                            new RegExp(this.term, "gi"),
                            "<span class='ui-state-highlight'>$&</span>");
                    return $("<li></li>")
                            .data("item.autocomplete", item)
                            .append("<a>" + newText + "</a>")
                            .appendTo(ul);
                };
            }
        }
    });
