Ajax异步获取html数据中包含js方法无效的解决方法

function data() {
        var tab = $("#dic")
        $.ajax({
            url: ‘../demo.ashx?method=GetList‘,
            data: {},
            dataType: ‘json‘,
            type: ‘post‘,
            async: true,
            success: function (data) {
                //console.log(data);
                var parentStr = ‘‘;
                $.each(data, function (i, item) {
                    //console.log(item.text);
                    
                    parentStr += "<div class=‘pull-right‘> <a class=‘morechange‘ href=‘javascript:;‘ style=‘visibility: visible;‘>更多+</a></div>"

});
tab.html(parentStr);
}
})

}

$(‘.morechange‘).click(function(){
    alert("弹出")
});

$("#dic").delegate(‘.morechange‘, ‘click‘, function () { alert("弹出"); });
