Changed function is not firing?

I have ragdoll script that creates BoolValue inside Character and changes character state from not ragdoll to ragdoll and so on. When i started testing it by changing BoolValue value with mouse clicker (very fast) turns out it is not firing sometimes and causes glitches

local events = game:GetService("ReplicatedStorage"):WaitForChild("Events").Player

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
		local ragdoll = Instance.new("BoolValue", char)
		ragdoll.Name = "ragdoll"
		ragdoll.Value = false
		local cool = false
		joints = {} welds = {} fakeLimbs = {}
		ragdolling = false
		ragdoll.Changed:Connect(function(newVal)
			local ragdollChar = coroutine.wrap(function(char)
					events:WaitForChild("RagdollCameraOn"):FireClient(player)
					char.Humanoid.JumpPower = 0
					char.Humanoid.Jump = false

								joints[this.Name] = {this,this.Part0}

						end
					end

						limb.Position = position;limb.Size = size;limb.Transparency = 1
						fakeLimbs[#fakeLimbs+1] = limb

end)

What other function or thing i can use to avoid this glitch?

So unless I'm misunderstanding, you click to update the BoolValue 'radgoll', and unless there's more server-side code you're not showing, you're doing that update in the LocalScript.

If that's the case, ragdoll.Changed won't fire on the server because changes made by the client are local - i.e., they won't replicate; the server won't see it.

I'd just fire an event on mouse click and connect that to the ragdoll/unragdoll function.
