popup to confirm a "delete" action

Hello,

I created a layer that allow you to delete some data in  database. I would like to create a popup that would appears when the user click on delete, and where it would be written something like "are you sure you want to delete this row ?"

if he would click on "confirm", it would delete. Otherwise, if would on cancel, nothing would happen.

the problem is I am not able not lauch the delete action only if he clicked on "confirm". Can somebody help me please?

Thank you

Regards

Damien
