实时搜索框返回旧的搜索结果

Question

所以，我的网站上有一个实时搜索框但是当我输入另一个不相关的产品时，它有时会返回列表顶部的旧结果，所以我想知道我的代码中是否有不对的内容一些额外的代码可以修复此问题如果看起来不对劲，请问我。我很乐意回复。完整代码共享：https://codeshare.io/5eKyvL

var delay = (function () {
        var timer = 0;
        return function (callback, ms) {
            clearTimeout(timer);
            timer = setTimeout(callback, ms);
        };
    })();
var initSearchEvents = function () {
        getElement().keyup(function (e) {
            var value = $(this).val();
            if (e.keyCode === 13) {
                e.stopPropagation();
                var data = {
                    title : value
                };
                if (value.length >= getMinchars()) {
                    searchRedirect(data);
