Bound translateable element attributes

Working example here:
http://emberjs.jsbin.com/dopoz/2/edit

Using "data-bindtranslateattr-xxx" as to not confilct with regular bound attributes.
Short version I'm sometimes pedantic.
Long one: I don't really care if one declare variables using only one var statement or with several, if each get its own row or if all are declared in the same, but I think it's good to declared all variables in the same way.
Guess I just stumbled upon that one..
