Dashboard Not Refreshing

I have a dashboard that has a button tile that when pushed updates a date-time hub variable that is displayed on the same dashboard.

When I press the button, the displayed variable does not change unless I close out the dashboard and then re-open the dashboard.

How do I get the dashboard to refresh the display of the hub variable (without closing & opening the dashboard)?

there's a number of ways to accomplish the refresh like a redirector page, etc.

I use
Toggle Cache – Get this Extension for 🦊 Firefox (en-US)strong text
during dev work to turn off Firefox caching. Works well for ajax stuff on forms as well ...

If you tap the little green check mark in the upper right corner, the dashboard page will refresh.
