function Response(xhr, error, success) {
    if (!isJson(xhr.responseText)) {
        console.error('Response give not JSON Data');
        // alert('Response give not JSON Data');
        console.log(xhr.responseText);

console.log looks like debug code. Are you sure you do not want to remove it?

        return false;
    }
    var data = JSON.parse(xhr.responseText);
    if (xhr.readyState == 4 && xhr.status == "200") {
        // console.table(data);
        success(data, xhr);

There is no return statement in this branch, but you do return something in other branches. Did you maybe miss it? If you do not want to return anything, consider adding return undefined; explicitly.

    } else {
        // console.error(data);
        error(data, xhr);
