Changing ng-model for input inside ng-repeat based on content

I have an exercise where I have to be able to customise some options of a laptop. I'm loading this options from the database. There are four possible options: RAM,Processor,Video,Screen. For the input model, I would like to set the

ng-model
respectively.

<div class="text-center">
<div class="marginTop">

<p>{{laptop.selected.text}}</p>

<div class="row" ng-repeat="x in laptop.customize">
<div class="col-xs-3">
<p>{{x.name}}</p>
</div>
<div class="col-xs-9">
<label class="radio-inline" ng-repeat="y in x.options">
<input type="radio" name="{{x.name}}" ng-model="laptop.selected.{{x.name}}" ng-value="y.description"> {{y.description}}
</label>
</div>
</div>

<div class="col-xs-12">
<a href="#order" ng-click="laptop.save()" class="btn btn-default" type="submit">En door</a>
</div>
</div>




The goal would be to set
ng-model="laptop.selected.RAM"
or
ng-model="laptop.selected.Processor"
, but I can't find any way to do so.

Excuse my html, I'm a noob.

[edit]
JSON in laptop.customize

Answer

You just set like this, since you already hold the values in y, also you can get the selected value using ng-change

<div class="marginTop">
    <p>{{laptop.selected.text}}</p>
    <div class="row" ng-repeat="x in laptop.customize">
        <div class="col-xs-3">
            <p>{{x.name}}</p>
        </div>
        <div class="col-xs-9">
            <label class="radio-inline" ng-repeat="y in x.options">
                <input type="radio"  name="{{x.name}}" ng-model="laptop.selected[y.name]" ng-change="getselected(y)"  ng-value="y.description">            {{y.description}}
            </label>
        </div>
    </div>
    <div class="col-xs-12">
        <a href="#order" ng-click="laptop.save()" class="btn btn-default" type="submit">En door</a>
    </div>
</div>
