Custom onBurnt / Listening to onburnt / extra functions

[MatH16]

local function onburnt(inst)
    inst.SoundEmitter:PlaySound("phonograph/end")
    inst.SoundEmitter:KillSound("phonograph/play")
    DefaultBurntStructureFn(inst)

    inst:AddTag("burnt")
    inst:PushEvent("turnedoff")
end

How do I make it so I get the normal effects of a burnt structure (coal drops etc.) but I can do extra stuff when onburnt happens?

I tried with this as well, but did not get it working either way
 

local function OnBurntPhonograph(inst)
    inst:PushEvent("turnedoff")
    inst.SoundEmitter:PlaySound("phonograph/end")
    inst.SoundEmitter:KillSound("phonograph/play")
end

inst.ListenForEvent("onburnt", OnBurntPhonograph)

I'm happy about any help - thanks in advance!!
