Firstly I love your gourd pot - a very novel and attractive container! Sounds like you've done everything right. Re: trying to get keikis from a cut spike; I have had very limited success by sticking the cut spike into wet sand. If you can get 'Keiki Grow' and dip the cut end into it and rub some over the 'eyes' you might get better success rate. A few of our members have posted regarding the use of Keiki Grow. I normally leave the old spikes on the plant until they dry up, but since you're repotting, it would be prudent to cut it off so that all the energy would go into establishing new growth.
