How to Update Editor widgets value C++

Is it possible to update all opened editor’s windows when I change the package value?
For example: I have my editor for DataTables. If I change a value in the package I mark it like “Dirty”. So if I close the editor after it asks me if I want to save this package. I save it and everything works well. But if a default DataTable editor is opened at the same time with this package, this editor tab shows the old value. After I reopen the editor window, the value refreshes to the new one.
So does anybody know how to refresh the window without reopening it or notify the editor to refresh the windows?
