Changing loadTextURL

I have an InPlaceEditor, when it is clicked on it loads the unformatted 
textile text from the server. When i click on menu items, I change the 
content to the formatted text and i want to change the file the 
InPlaceEditor will load.
I thought a simple

loadTextURL: "getPage.php?page=" + currentPage;

would do. But currentPage is always empty... It's baffling :p
Is there a way to fix this problem, or perhaps, is there a better way of 
going about this?

Thanks.
