How to refresh a widget

Hi,

I have a process built in Bonita 7.1.2. and I've made a summary page for all the active cases. I use some widgets as a Data Table, texts, etc.

My question is, how can I put a button or something that refreshes the data on the summary page? I don't want implement a method that refreshes the window, I only want to refresh the Data Table.

Thanks in advance.

David.
