Как сортировать данные JSON в ng-repeat?

Я получаю ответ сервера и привязываю эти данные к просмотру с помощью ng-repeat. Теперь я хочу отсортировать эти данные на priceList и name. Я могу сортировать имя, используя orderBy, но не с priceList. Я хочу сортировать продукты на основе priceList. Сортировка с именем изменяет порядок списка, а сортировка на priceList будет производить только порядок products для каждого category. Он будет влиять на порядок отображаемой категории. Пожалуйста, помогите мне решить это.
Мой код:

<div ng-controller="Ctrl">
    <pre>Sorting predicate = {{predicate}};</pre>
    <hr/>
    <table class="friend">
        <tr>
            <th><a href="" ng-click="predicate = 'name'; reverse=false">Name</a>
            </th>
            <th><a href="" ng-click="predicate = 'priceList'>price</a></th>
        </tr>

    </table>


<div ng-repeat="data in _JSON[0].categories | orderBy:predicate">
       <div ng-repeat="vals in data.itemTypeResults |orderBy:'partTerminologyName'" id="{{vals.partTerminologyName}}">
`<h4 style="background-color: gray">{{vals.partTerminologyName}} : Position :{{vals.position}}</h4>`<br>


<div ng-repeat="val in vals.products">
    <b> Quantity:{{val[0].perCarQty}}</b><br>
    <b> part:{{val[0].partNo}}</b><br>
    <b>sku:{{val[0].sku}}</b><br>
    <b> qtyInStock:{{val[0].qtyInStock}}</b><br>
    <b> priceList:{{val[0].priceList}}</b><br>
    <b>priceSave:{{val[0].priceSave}}</b><br>
    <b> qtyDC:{{val[0].qtyDC}}</b><br>
    <b> qtyNetwork:{{val[0].qtyNetwork}}</b><br>
    <b> priceCore:{{val[0].priceCore}}</b><br>
        </div>
</div>      
    </div>
