Localizing templates with backbone, underscore on mobile

I want to localize templates in my Phonegap/Backbone mobile App. I want to somehow override underscore render function in a way that would always append extra attribute with languages. Let me show that on example:

lets say I required (require.js) the HomeView template wich looks like:

<div>
   <p><%= language.get('someText') %></p>
</div>

In my HomeView.js I have:

var template = _.template(HomeTemplate);
this.$el.html( template({language: LanguageModel}));

This works, but I don't want to always append this language attribute to underscore template. Could I somehow overwrite that render function so It would always include language Model?

You can put any JavaScript expression you like inside <%= ... %>. In particular, you can access globals. So, if you have a global application namespace:

// I'll call it `app` for lack of a better placeholder.
window.app = { ... };

Then you can put language in there:

app.language = your_language_model;

and access it in any template without supplying anything extra to the _.template call or the compiled template function:

var t = _.template('<%= app.language.get('pancakes') %>');
var h = t();
