I have learned to put them in part sun/part shade and to wait as patient as you can get. 2 weeks is still short..sometimes it takes a month or more, just depends on the cultivar and the prevailing temperatures you have there. My Plumeria Celadine did not drop all her leaves, but somehow it is doing a reverse, it got more leaves in Dec and Jan than right now in April..ah, the quirkiness of these plumies.
My other noid Plumie is in similar leaf claw stage like your cutting. Been outside since mid-March. Our temps went down a bit, so it decided to just go an stasis, but now we are back in the high 80's so I can see the leaf claw go very red and with that misty tip.
Just resist the urge to water, till you see at least one fully formed leaf.
