How to repeat data in JSON?

I feel like I’m close but the data is not repeating.

This is the data stored in a JSON field within the database.

{
    "Body": [{
            "name": "slender",
            "amount": 7496,
            "parentName": "Body"
        }, {
            "name": "sturdy",
            "amount": 2500,
            "parentName": "Body"
        }
    ],
    "Gender": [{
            "name": "female",
            "amount": 4999,
            "parentName": "Gender"
        }, {
            "name": "male",
            "amount": 4997,
            "parentName": "Gender"
        }
    ]
}

This structure returns the first name value, but not the second name value. Any ideas why?

            <div class="row" is="dmx-repeat" id="repeat1" dmx-bind:repeat="getCollection.data" key="id">
                <ul dmx-text="checkboxes.Body[0].name">
                    <li dmx-text=""></li>
                </ul>
            </div>
