How to add UCurveFloat to FTimeline?

I am working on c++ Sliding doors. I use blueprint to derive from my C++ base class and set UCurveFloat component.
As i assume, UCurveFloat define timeline when FTimeline is responsible for timeline playback. So i need to add my UCurveFloat to FTimeline and call play() but i don’t know to do that, can someone help me? :smiley:

i got the timeline working but the function is only called once.
