How to use Ember Concurrency with Octane

my-octane-component.js

// Octane

import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';
import { task } from 'ember-concurrency';

export default class MyOctaneComponent extends Component{
  @tracked status = null

  @(task(function * () {
    let nums = [];
    for (let i = 0; i < 3; i++) {
      nums.push(Math.floor(Math.random() * 10));
    }

    this.status = `My favorite numbers: ${nums.join(', ')}`;
  })) pickRandomNumbers;
};

old-classic-component.js

// classic component for comparison. See http://ember-concurrency.com/docs/task-function-syntax/

import Component from '@ember/component';
import { task } from 'ember-concurrency';

export default Component.extend({
  status: null,

  pickRandomNumbers: task(function * () {
    let nums = [];
    for (let i = 0; i < 3; i++) {
      nums.push(Math.floor(Math.random() * 10));
    }

    this.set('status', `My favorite numbers: ${nums.join(', ')}`);
  }),
});

Hello @jenweber
I use ember-concurrency with ember octane. can you explain with handlebars?
I try to set pickRandomNumbers on button.

<button type="button" {{on 'click' this.pickRandomNumbers}}>CLICK </button>

but it can't work. So, I add @action decorator with task

  @action
  @(task(function * () {
    let nums = [];
    for (let i = 0; i < 3; i++) {
      nums.push(Math.floor(Math.random() * 10));
    }

    console.log(`My favorite numbers: ${nums.join(', ')}`)
  })) pickRandomNumbers;

It can't work too.

Finally I use action for call perform task

  @(task(function * () {
    let nums = [];
    for (let i = 0; i < 3; i++) {
      nums.push(Math.floor(Math.random() * 10));
    }

    console.log(`My favorite numbers: ${nums.join(', ')}`)
  })) pickRandomNumbers;

  @action
  callPickRandomNumbers() {
    this.pickRandomNumbers.perform()
  }

<button type="button" {{on 'click' this.callPickRandomNumbers}}>CLICK </button>

It works. but how can I use perform keyword with on ?

<button type="button" {{on "click" (perform callAction)}}>Save</button> - this is how I call perform and it works
