UI lgtm

I would prefer a window.location.reload(false); after dismissing the dialog box
or (better) somehow triggering a refresh of the data but it's not a big deal so
unless you can do it easily don't bother too much.

I agree, when this dialog closes and there is any chance (successfully or not)
that bots were deleted, it should trigger a reload of the data. 
I believe it should be possible to do that without reloading the whole page.

Done.  It was fairly straightforward to do.
