How can a button trigger an ODATA Update function

Dear Experts,

i am new to the topics Fiori Apps and ODATA. I have the task to learn how to design a Fiori App. The App should do following:

Show the QM-Notifications of a specific type. Than u should be able to see a detail view of a Notification you selected. Within this detail view there is a Button to confirm the QM-Notification.

So far i was able to get the ODATA Service working. Which means i can select the DATA form the Table QMEL and show it on my Fiori App created with a template.

Now to my question:

How do i trigger the ODATA Update function to confirm the notification with the Button in the Fiori App. The coding in the backend is no problem. i tryed to google and read some documentations but i somhow cannot find how to trigger the update method from the odate collection with a button on the UI.

I would appreciate any guides or tutorials on how to do this.

If there is any other way to get this working i would like to know aswell.

Thank you in advance,

Jan
