Descendantadded not firing at all?

im trying to make it so that the enemy moves to the sound value parent's position but descendantadded is not firing...

local debounce = false
local prevpath = nil

workspace.DescendantAdded:Connect(function(sound)
    -- for i,sound in pairs(workspace:GetDescendants()) do
        if sound.Name == "Soundvalue" and sound:IsA("StringValue") then
                         print("Founded")
             local hrp = script.Parent:WaitForChild("Torso")
             local ischasing = script.Parent:WaitForChild("Ischasing")

             if ischasing.Value == false then
                 if not debounce then
                    debounce = true

                     if prevpath ~= nil then
                        prevpath:Destroy()
                     end

                    if sound.Parent and sound.Parent:IsA("BasePart") then
                        print("aaaaa")
                                  local path = game:GetService("PathfindingService"):CreatePath()
                        path:ComputeAsync(hrp.Position, sound.Parent.Position)

                        local waypoints = path:GetWaypoints()

                        prevpath = path

                        for i,waypoint in pairs(waypoints) do
                            if ischasing.Value == false then
                                script.Parent.Enemy:MoveTo(waypoint.Position)
                                script.Parent.Enemy.MoveToFinished:Wait()
                            end
                        end
                    end

                    debounce = false
                 end                
             end
         end
    --end
end)
