Change one name of a language

Hello. I can't find how to do it: how can I change "Cebuano" language name in Catalan, which now it is "cebuano", to the correct one, which is "cebuà"? PS: previsualization of this page don't work fine, perhaps?

Update the language translations in Catalan at CLDR.

The link should be to CLDR.

It worked :o) http://unicode.org/cldr/trac/ticket/2655 Thanks both! PS2:Previsualization continues not working...
