Updating Widget Source
Do you want to see an update during PIE (Play in Editor) or in the viewport above?
Which part of the widget is not updating?
What is the code responsible for updating it and how are you triggering it?
Are you expecting things to happen automatically in your widget (counters ticking) or you need to feed the widget external data?
Generally speaking, in order to update the widget component's embedded widget you access it by Get User Widget Object and cast it to the correct type - it's a shot in the dark as I'm unsure what is going on there at the moment.
Please do consider elaborating a bit more.
