Ember CLI generate component in an addon

I try to make an addon using ember-cli. Here it is step by step what I have done so far:

sudo ember addon test-addon
cd test-addon
sudo ember serve 

now the server runs and on localhost:4200 I can see the test/dummy app's application hbs.

Welcome to Ember.js

Its time to make some components for the addon:

sudo ember g component my-form

In the tests/dummy/app/templates/application.hbs I added {{my-form}}

And now I'm getting the following js error:

Uncaught Error: Could not find module test-addon/components/my-form imported from dummy/components/my-form
