Does Demon Stitcher No Longer Trigger Off of Barrier Invocation?

I'm trying to do a infernalist Barrier Invocation with recoup and Demon stitcher, but either something changed or I'm missing an important part of the build.

When I cast spells via Barrier Invocation, Demon Stitcher doesn't trigger and I have no way of recharging my ES.

I'm super confused as to what I'm doing wrong at the moment.
