Chaning camera's angle doesn't work?

local Camerachange = game.Workspace.Change
local touched = false
-- ================================================================

-- // Camera Variables

local CamOffset = Vector3.new(10, 5.5, 20)
local CamLookDirection = Vector3.new(0, 0, -1)
local angle = CFrame.Angles(0,-45,0)

local camera = game.Workspace.CurrentCamera
local player = game.Players.LocalPlayer
local RunService = game:GetService('RunService')


-- ================================================================

Camerachange.Touched:connect(function(hit)
    if not touched then

        touched = true
        wait(1)
        print("I've passed!")
        -- ================================================================

        -- // Stuff

        local function setupCamera()
            camera.CoordinateFrame = CFrame.new(player.Character.HumanoidRootPart.Position + CamOffset,
                             player.Character.HumanoidRootPart.Position + CamOffset + CamLookDirection)
        end 

        player.CharacterAdded:connect(setupCamera)


        local function onUpdate()
            if player.Character and player.Character:FindFirstChild('HumanoidRootPart') then
        camera.CoordinateFrame = camera.CoordinateFrame:lerp(
                                 CFrame.new(player.Character.HumanoidRootPart.Position + CamOffset,
                                 player.Character.HumanoidRootPart.Position + CamOffset + CamLookDirection), 0.2 )
        end
    end

    -- ===

    -- // Changing Angles

    camera.CoordinateFrame = angle  


    -- ===
    RunService:BindToRenderStep('Camera', Enum.RenderPriority.Camera.Value, onUpdate)
        -- ================================================================ 

        touched = false 


    end
end)

It changes it to -45 angle for a milisecond, but then it goes on default again, any fix to it?
