Dynamically changing selectionObjectName to different part of the Same node not working properly

@STMax wrote:

I have node template as shown below and a click event handler for each of the individual parts in the Node Template. When clicked I am changing the selectionObjectName dynamically to highlight the specific part that was clicked. But the selection (blue highlight) in not setting consistently when I click between the different parts with in the node template. Please let me know if my approach is not correct or if I am missing something. Thanks.
