Humanoid Jump Power resetting after death?

Im trying to make a game where every second you jump power gets higher and higher and when the player dies it just resets the players jump power.At the start of the game you press a button to start the jump loop. Here is the 2 scripts. There is also a intvalue called jumpPower and a remote event called jump

server script in server script service

local Jump = game.ReplicatedStorage.Jump
local jumpPower = game.ReplicatedStorage.JumpPower


Jump.OnServerEvent:Connect(function(plr)
    print("event called")
    local char = plr.Character
    jumpPower.Value = 2
    local humanoid = char:FindFirstChild("Humanoid")
    function Jump()
         while wait(1) do
            jumpPower.Value += 1.5
            humanoid.JumpPower = jumpPower.Value
            wait(1)
            print(humanoid.JumpPower)
        end
    end

    Jump()

    plr.CharacterAdded:Connect(function(char)
        char:FindFirstChild("Humanoid").JumpPower = jumpPower.Value

    end)

end)

local script

local plr = game.Players.LocalPlayer

local Button = script.Parent.TextButton
local Label = script.Parent.TextLabel
local door = game.Workspace.Door
local debounce = false
local char = plr.Character
local jumpPower = 2
local jump = game.ReplicatedStorage.Jump


Label.Visible = false
door.CanCollide = true
door.Transparency = 0.2
Button.Visible = true


Button.MouseButton1Click:Connect(function()
    if debounce == false  then
        debounce = true
        Label.Visible = true
        for i = 5, 0, -1 do
            Label.Text = "Starting in "..i.." Seconds"
            wait(1)
        end
        Label.Visible = false
        door.CanCollide = false
        door.Transparency = 1
        Button.Visible = false
        jump:FireServer(plr)
    end

end)
