How to makes this check over and over each 2 seconds?

Is their anyway make this checking every 2 seconds, because now it only counts when an player joins but I have over 150 badges so when an player find a new one i want the value goes up but now it doesn't check agian each 2 seconds. Someone know how? Btw I do like to not change line 2 beacuse I already did put in the orginal one 150 badges. Thanks alot!

local BadgeService = game:GetService("BadgeService")
local badges  = {229929415, 229929797, 229929912}
while true do
wait (2)
local function countBadges(player)
    local numBadges = 0
    for _, badge in next, badges do
        if BadgeService:UserHasBadge(player.userId, badge) then
            numBadges = numBadges + 1
        end
    end
    return numBadges
end

game.Players.PlayerAdded:connect(function(player)
    local stats = player:WaitForChild("leaderstats")
    local cash = stats:WaitForChild("Badge")
    cash.Value = countBadges(player)
end)
end

This might work:

function countBadges(player)
    local numBadges = 0
    for _, badge in next, badges do
        if BadgeService:UserHasBadge(player.userId, badge) then
            numBadges = numBadges + 1
        end
    end
    return numBadges
end

local BadgeService = game:GetService("BadgeService")
local badges  = {229929415, 229929797, 229929912}

game.Players.PlayerAdded:connect(function(player)
    local stats = player:WaitForChild("leaderstats")
    local cash = stats:WaitForChild("Badge")
    cash.Value = countBadges(player)

    while true do
	wait (2)
	countBadges(player)
    end
end)
