filterBy @each bug

controllers.application.js

import Ember from 'ember';
import computed from 'ember-macro-helpers/computed';
import raw from 'ember-macro-helpers/raw';
import { filterBy, first } from 'ember-awesome-macros/array';

export default Ember.Controller.extend({
  data: [
    Ember.Object.create({ filter: 0, label: '1' }),
    Ember.Object.create({ filter: 1, label: '2' }),
    Ember.Object.create({ filter: 1, label: '3' }),
  ],
  
  filteredData1: first(filterBy('data', raw('filter'), 1)),
  filteredData2: first(filterBy('[email protected]', raw('filter'), 1)),
  filter: filterBy('data', raw('filter'), 1),
  filteredData3: first('filter'),
  
  actions: {
    test() {
      this.data[0].set('filter', 1);
    },
  },
});

templates.application.hbs

<p>First item with filter=1 without .@each: {{filteredData1.label}}</p>
<p>First item with filter=1 with .@each: {{filteredData2.label}}</p>
<p>First item with filter=1 without composing: {{filteredData3.label}}</p>
<button {{action 'test'}}>Test</button>
<p>All the items should find '1' after you press the test button</p>
