Force render in PremierePro using AfterEffects SDK

I'm working on a plugin created in the AfterEffects SDK, but now I need to run it on Premiere Pro.
The plugin connects AfterEffects to another app with websocket, which sends me some frames data.
I'm handling the frame data in a separate thread. As soon as I receive frames data in a separate thread, I want Render to be called so that the user can see the frames.

However, when I play the frames in PremierePro, FrameSetup is called for every frame but Render isn't. 
As of now, I have Rendered my data in the FrameSetup only. But that is also called when I play. Atleast the preview frame should be visible as soon as I receive data from the other app.

In AfterEffects, when I received data from the other app, I changed a param value as suggested by @shachar carmi  sir. But that doesn't work for me on PremierePro.
