Bug : onchange modification of selection does not work

[lucaslaurent04]

When modifying selection in onchange method of a Model, the select options are not updated.

Note:

• Modification of the value work.

public static function onchange($event, $values) {
    $result = [];
    if(isset($event['type'])) {
         $result['subtype'] = [
             'value' => MAP_TYPES_SUBTYPES[$event['type']][0],
             'selection' => MAP_TYPES_SUBTYPES[$event['type']]
         ];
    }

    return $result;
}

In the example above the value is updated in the front-end but not the selection.
