You probably mean to connect to the "destroy-event" signal in the above
though it's not likely that you need to handle it.

The above line is what is destroying your dialog - remove it.

You are mixing the two ways of using a dialog - show() and run(). You
should only use one of these ways. If you use the show() method then add
a call in delete() to hide() the dialog when you are finished the delete
processing. If you use the run() method then you don't need to handle
the delete-event and you should retrieve the return response from the
run() method to figure out what to do (you also don't need to make the
dialog modal since run() blocks the UI until it returns).
