Accessing an Ember.Mixin within a custom handlebars helper - ember.js

Question

Is there an elegant way of using methods defined in an Ember.Mixin object within a custom handlebars helper?
For example, in my case I have a mixin, App.Format which contains a bunch of different methods for formatting numbers, dates, ect and I would like to make some of these methods accessible directly from templates via custom helpers (e.g. {{formatNumber 450324}}). The reason I don't just put the method implementation directly in the helper instead of the mixin is that I also need these methods to be available in controllers, views, ect. And in the interest of keeping my code DRY, I definitely do not want to have duplicate code in the mixin and the helpers.
Is there any canonical, "emberish" way to accomplish this, or am I just thinking about it in the completely wrong way altogether?
Edit: Here is a jsbin to better illustrate the problem:

Answer 1

The method Mixin.apply makes the job.
Ember.Handlebars.helper('formatNumber', function(num, decimals) {
var format = App.Format.apply({});
return format.formatNumber(num, decimals || 2);
});

I am using Ember 2.12 and this is what I worked for me. Hopefully this helps somebody.
Create a new mixin named formatter:
../mixins/formatters.js
import Ember from 'ember';
export default Ember.Mixin.create({
shortDate: function(date) {
return `Date should be formatted: ${date}`;
}
});
Create a new helper that imports the above mixin and uses it.
../helpers/short-date.js
import Ember from 'ember';
import FormatDateMixin from '../mixins/formatters';
export default Ember.Helper.extend(FormatDateMixin, {
compute: function(params /*, hash*/) {
return this.shortDate(params);
}
});
In the template *.hbs file, use the helper as below:
{{short-date today}}
