I'm using UI-O-Matic and I would like to save json in one of my custom table properties. I created a Custom Property View:

<ul ui-sortable="sortableOptions" ng-model="property.value" class="textstring-row-set">
        <li ng-repeat="command in property.value" class="textstring-row-field">
            <input class="umbEditorTextField" type="text" ng-model="command.key" />
            <input class="umbEditorTextField" type="text" ng-model="command.value" />
            <input class="umbEditorTextField" type="text" ng-model="command.description" />
            <i class="icon icon-add" ng-click="addListItem($index)"></i>
            <i class="icon icon-delete" ng-click="removeListItem($index)"></i>
            <i class="icon icon-navigation handle"></i>
        </li>
    </ul>

And in my controller, I want $scope.property.value to be this json format:

'[{ "key": "command one", "value": "value one", "description": "description one" }]'

The view works fine, but when I try to save the page on create, I get an 'Unexpected character encountered' from Newtonsoft.Json.JsonTextReader.

Is this not the correct way to store JSON in my property with UI-O-Matic? Or do I need to extend it to take JSON as a property value?
