serialize array object must be PlainObject?that is why?

demo 1:
`
class Info
{
FieldName: string = null;
Desc: boolean = false;
}

  const _info = new Info();
  _info.FieldName = "abc";
  _info.Desc = true;

  let _obj = {
    qModel: { SortInfoArray: [_info] }
  };

`
form data:
qModel[SortInfoArray][0][]: abc
qModel[SortInfoArray][0][]: true

demo 2:
let _obj ={ qModel: { SortInfoArray: [{ FieldName: "abc", Desc: true }] } };
form data:
qModel[SortInfoArray][0][FieldName]: abc
qModel[SortInfoArray][0][Desc]: true

sorce code
`

    function serialize(params, obj, scope) {

    var array = isArray(obj), plain = isPlainObject(obj), hash;

    each(obj, function (value, key) {

    hash = isObject(value) || isArray(value);

    if (scope) {
        key = scope + '[' + (plain || hash ? key : '') + ']';
    }

    if (!scope && array) {
        params.add(value.name, value.value);
    } else if (hash) {
        serialize(params, value, key);
    } else {
        params.add(key, value);
    }
});

}

I have same issue. It seems the plugin removes / stops whenever it reaches "{".
The jQuery alternative does not do that.
