How to use setDataHandler() to edit/change report cell data

Summary:

Content (required):

Hi, 

I am developing a BUI report extension to update report cells of an existing report.

For this I use the setDataHandler callback. The callback looks ok when I console.log it but the report data is not updated when the report is executed.

See code snippet below for more details

Any ideas on why this isn't working of any suggestions on what I could be doing differently?

Thanks,

Martin S.
