title: Use ngx-translate in component
body: <p>I'm using ngx-translate with no-problems in views, using pipes. What i need to do is to use it in a component, for example to show an error message, or define a datatable column default content.</p>
  
  <p>I'm trying to do something like:</p>
  
  <pre><code>translate.instant("AREA.NEW");
  </code></pre>
  
  <p>or</p>
  
  <pre><code>translate.get("AREA.NEW").subscribe((res: string) =&gt; {
      console.log(res);
  });
  </code></pre>
  
  <p>I've tried calling it in ngOnInit() and ngAfterViewInit()</p>
  
  <p>But in both cases i just get "AREA.NEW", not the translated word. I asume the json dictionary is loaded after my call, so i don't realize how make it work.</p>
