localization

[openmotion]

hello
how can i change the language of a timeline ?
my example is : http://visjs.org/examples/timeline/other/localization.html

this my setup

$scope.timelineOptions = {
locale:'fr',
height:"100%",
groupOrder: 'content' // groupOrder can be a property name or a sorting function
};
but no change

my version of moment is :
http://cdnjs.cloudflare.com/ajax/libs/moment.js/2.8.1/moment-with-locales.min.js

thanks for your help
