function ajaxeo(url, data, method){
    $.ajax({
        url: url,
        type: method,
        data: data,

        if (this.innerHTML == $(this).attr('data-orig')) {
            // no change

        else {
            // change has happened, store new value
            $(this).attr('data-orig', $(this).html())
            cambio($(this).attr('dataId'), $(this).html());

你传错了参数

ajaxeo("includes/php/ajax/changeProvider.php?oldID="+ID, "post", {"newVal": newValue});

应该是

ajaxeo("includes/php/ajax/changeProvider.php?oldID="+ID, {"newVal": newValue}, "post");

错误可能是 jQuery 试图确保方法是大写的
