In Ember, how can I handle an action sent from a controller in another controller

I have a controller A that sent an action with this.send('makeItHappen'), and I want to handle it in controller B. How do I do it?

JS:

// Controller A
import Ember from 'ember';

export default Ember.Controller.extend({
  actions: {
    sendToDataCenter() {
      this.send('makeItHappen');
    }
  }
});


// Controller B
import Ember from 'ember';

export default Ember.Controller.extend({
  actions: {
    makeItHappen() {
      console.log('It works!!'); // this throws an error
    }
  }
});

In Controller B, it throws an error: Uncaught Error: Nothing handled the action 'makeItHappen'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble.

Please, can anyone help? Thank you.
