Actually i using the required procedures and read the whole thread about how to create custom leaf decays.
Its working in the way if i place it by my hands but not working when i set up my custom wood block and custom leaf block in a custom biome. What should i do? Is this a bug because i think i won't forget anything and read the required article 321312x times and as it works manually but not automate generated biomes i think its a bug like thing. :/

This is what i'm using and its actually working but leafs dissappearing instanty.
This was covered on tracker many times before.
When a word is generating, tick updating is not triggered as this would cause the world lag beyond imagination if all blocks just started ticking.
What you can do is use on neighbour block changed procedure trigger and when this happens, use Schedule block tick procedure block to start ticking of a leaf block that will then start doing decay logic.
This will make sure leafs will start decaying once the log blocks next to them "change" - get removed.
