can anbody provide me complete example of jamesarosen/ember-i18n when changing language from select menu?

i have used jamesarosen/ember-i18n in my project. but I don't know how to use into my code so that I can switch languages from the select menu.

for example

If I change the language from English to hindi from the select menu

{{ hello }} // output is hello in english 

should change to

{{ hello }} // output is नमस्कार in Hindi

Would be great if someone can quote an example
