BC pop up alerts and shooping cart strings

Question

Hi everyone,
I am trying to make custum  alert messages in Portuguese on a BC website using this code from : Customizing Online Shop Alert Message Strings
and also customize the online shop layout strings like "Shoping cart is empty! continue shooping " and  "1 item(s), Total: €12,00 VIEW CART"
to "Carrinho de compras vazio! continuar as compras." and "1 item(s), Total:€ 12,00 VER CARRINHO DE COMPRAS"using this piece of code i found somewere here on the forum too:
" <script type="text/javascript">
var ele = GetElementsByClass('cartLink');
if(ele[0])   ele[0].innerHTML = 'O CARRINHO DE COMPRAS EST&Agrave; VAZIO!';// replace with your own message!
  function UpdateProductExtras(c, p, res) {
  document.getElementById('catCartDetails').innerHTML = 'O carrinho de compras est&aacute; vazio! <a href="/catalogos">VOLTAR</a>'; // replace with your own message!
var ele = GetElementsByClass('cartSummaryItem');
if(ele[0])   ele[0].innerHTML = 'Carrinho de compras vazio.';// replace with your own message!
  function UpdateProductExtras(c, p, res) {
  document.getElementById('cartSummaryItem').innerHTML = 'Carrinho de compras vazio.'; // replace with your own message!
var ele = GetElementsByClass('cartSummaryLink');
if(ele[0])   ele[0].innerHTML = 'Ver carrinho de compras >';// replace with your own message!
  function UpdateProductExtras(c, p, res) {
  document.getElementById('cartSummaryLink').innerHTML = 'Ver carrinho de compras >'; // replace with your own message!
</script>"
The piece of code works, but everytime BC fires a pop up window, like wen we add a new product to the shoping cart or wen we hit the empty shoping cart button, they go back to the original strings in English, and only when we refresh the browser or move to another catalog and continue shoping, the messages go back to Portuguese.
How can i Fix this?
The same happens to the pop up window messages from the js file from Customizing Online Shop Alert Message Strings, only change to Portuguese if we refresh the browser.

Place the code further down in the page perhaps, also sounds like a caching problem, is it the same in all browsers?
