orderBy proprety

[arizona2014]

I've managed to display the elements in the loading order which is not enough for me. My object has a proprety called elementType and I'd like to display those elements first and the rest of elements after.

I've tryed with no success :
source="elements | orderBy:'elementType' "
source="elements | orderBy:'card.elementType' "
source="elements | orderBy:'elements.elementType' "

Did you ever solve this?
