How to register callback on vCenter selector

The Html Bridge documentation mentions that vCenter selector can be enabled using <showVCenterSelector>true</showVCenterSelector> tag.

I can access the the selected vcenter details from getVcSelectorInfo() API.

However, how do i register callback on this vCenter selector? I want to update the view and render details whenever a different vCenter is selected from the drop-down box.

Can you please provide additional details.

Thanks.
