Hey Alberto,
You can do this by creating a NPE ,
Now add the data view on the page where you want to impliment your logic,
Now, set the data source of your new dataview to microflow and add a create activity which creates the NPE object.
Now put your old dataview in your new data view, and now apply an on change event on the text boxes which refreshes the NPE object, and then apply your own logic for calculated attribute change.
This will lead to data view being refreshed and ultimately your own dataview being refreshed.
But make sure that your caculated attribute doesn’t change on the base of your textboxes.
HOPE IT HELPS!
