How to create Curves adjustment layer using Javascript?

It's odd, sometime scriptlistner records the settings, and other times it doesn't.

Bonjour

I use pipettes - white gray black (script) - the result is written in a text file - called a script to change the Curves adjustment layer.

Mais le tout en francais........

You can use scriptlistner to create the curves adjustment layer, but I'm not sure how you can add values to the curve.
