Ember model reloading in interval

ember.js ember-data

I have a User model, which has latitude and longitude properties, which are used to show current user location on map.

App.User = DS.Model.extend({
    firstName: DS.attr('string'),
    lastName: DS.attr('string'),
    email: DS.attr('string'),
    jobs: DS.hasMany("App.Job"),
    latitude:   DS.attr('number'),
    longitude: DS.attr('number'),
    measuredAt: DS.attr('date'),
});

What is the best way to autoupdate latitude and longitude properties from server every given interval? Does ember-data support this kind of use case? I can't find any samples with this functionality. I think I will need to override find method for User class with setInterval in it, is this the right approach?

Thanks

EDIT: Please see Dmitri Zagidulin's answer.

So I figured it out. For now all I need was to override didLoad method on model, in future I will probably need more complex solution, but this is adequate for now.

didLoad: function(){
  var self = this;
  setInterval(function() {self.reload()}, 5*60*1000); //every 5 minutes
}

In case someone needs to reload more models, good solution would be to implement this as Mixin.
