EmberJs: Component action not triggered in pagination example

I followed this pagination tutorial but can't get the "next-page" / "prev page" to work. http://webcloud.info/blog/2014/11/01/building-a-real-world-pagination-with-ember-js-the-right-way/

The alert never runs in the click event, any idea what I'm doing wrong?

Myapp.PaginatonBaseComponent = Ember.Component.extend({  
 tagName: 'button',
 classNames: 'btn btn-default'.w(),
 attributeBindings: ['disabled'],
 enabled: true,
 disabled: Ember.computed.not('enabled'),
 action: null,
 click: function(){
  alert('not triggered!');
  this.sendAction();
 }
});
