Anchor doesnt save

In packaged game i can create anchor but i cant save anchors that i created. The code is like below but it doesnt call binded function.

i am trying to debug it but in rift mode even CreateSpatialAnchor function delegate doesnt work(which is working packaged game).
i could not figure it out why save anchor delegates is not called.
if you need more detail, i can explain more. Thanks..
