Save Function for embedded excel Sheets

Save Function for embedded excel Sheets

I have managed to embed an excel file that was uploaded to Zoho. It's just a simple spreadsheet with milestones that need to be met versus employees. Once complete they have to option to click the dropdown and select an option but for some reason, I can not figure out how to get it to save after they update it.
 
Basically we change one selection, refresh page and it just shows the original document and publishing it just seems to show the image.
 
Thanks
