placing blocks by procedure

I have tried it multiply times and it don't work as it should.

It the procedure places blocks, but they only are placed, with fire it places and fire sets you on fire. But when I delete block under fire, it still burns but on nothing. It looks like it stops burning when you change neighbour block second time (also it never destroy/burn blocks like planks and other). I have tried "update/notify" after placing it, on server side, normally, and on both, I also tried "schedule tick update" but nothing changes, what can I do?
