Support for ButtonGroup in reactive forms to select a sinlge value. It would be great if it would work with typescript enums.

Hello Telerik Team,

I would like to propose a feature request: currently, the <kendo-buttongroup> is not keeping track of toggled button/s, so it would be a good idea to implement this. My solution right now is 

<kendo-buttongroup class="view-mode-group"
    selection="single"
look="flat">
<button class="group-button"
kendoButton
(click)="onChangeViewMode(0)"
[toggleable]="true"
[selected]="isModeSelected$(0) | async">Imported Messages
</button>
