How do I break a function with a TextButton?

So I have a script in Workspace, with a local script inside it. Inside the normal script is

game.Players.PlayerAdded:connect(function(player)
    script.LocalScript:clone().Parent = player.CharacterAdded:wait()
end)

Inside the localscript is

local target = workspace.GFrame --Location of target(the thing you want to spin around)
local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
camera.CameraSubject = target
local angle = 0
local begon = game.StarterGui.AtSpawn.AtSpawn.AtSpawn.Begin.TextButton --GUI Begin button
local bob = 0

function bobsdeath()
    bob = bob + 1
end

while wait() do --Spins camera
    camera.CoordinateFrame = CFrame.new(target.Position)  --Start at the position of the part
                           * CFrame.Angles(0, angle, 0) --Rotate by the angle
                           * CFrame.new(0, 0, 5)       --Move the camera backwards 5 units
    angle = angle + math.rad(1)
    if bob > 0 then break end
end

function begin()-- Returns cam to player
    game.Workspace.CurrentCamera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid 
game.Workspace.CurrentCamera.CameraType = "Custom" 
end

begon.MouseButton1Click:connect(bobsdeath,begin)

Whenever I click on the gui it does not end the function... Can someone help?
