Help with EventEmitter - Angular

I can not send one event to another, could anyone help me?

Basically what I am trying to do is that when I save something on component 1 it issues the event to component 2 so that the information is updated dynamically on the screen.

I've shared all the code in this link: link

If relevant here is a representation of the structure of my app.component:

<div class="wrapper">
    <sge-header></sge-header>
    <sge-aside></sge-aside>

      <div class="col-md-10 col-md-offset-2 content-custom">
        <router-outlet></router-outlet> 
      </div>
      <sge-footer></sge-footer>
</div>

Thank you.
