I want to create `eq` helper. It already exists in `ember-truth-helpers` addon, but I need only `eq` so I decided create it by myself in my plugin.  
I’ve created file `assets/javascripts/discourse/helpers/eq.js.es6` with such content:

```
import { registerHelper } from 'discourse/lib/helpers';

registerHelper('eq', function(params) {
  return params[0] === params[1];
});

```

and use it in template in this way:

`{{#if (eq param1 param2)}} <h1>hello</h1> {{/if}}`

But `eq` is not defined.

What is the right way to create helper?
