Why doesn't the TextLabel update with the humanoid's health?

I made a sort of boss bar where it displays the boss's current health and max health. Obviously it's supposed to update whenever it's health changes, but it isn't. There are no errors either. Here's my local script:

local healthLabel = script.Parent.Health
local boss = workspace:WaitForChild("BossMan")
local bossHealth = boss.Humanoid.Health
local bossMaxHealth = boss.Humanoid.MaxHealth

healthLabel.Text = bossHealth .. "/" .. bossMaxHealth
boss.Humanoid.HealthChanged:Connect(function()
	healthLabel.Text = bossHealth .. "/" .. bossMaxHealth
end)

Any help on this matter would be very appreciated.

you can try this

local healthLabel = script.Parent.Health
local boss = workspace:WaitForChild("BossMan")
local bossHealth = boss.Humanoid.Health
local bossMaxHealth = boss.Humanoid.MaxHealth

while true do
	wait()
	healthLabel.Text = bossHealth .. "/" .. bossMaxHealth
end

Solved it by myself after a while.
