title: How to fetch data from service without refreshing the page in Ionic?
body: <p><code>home.ts</code> fetches data from a service using the below code in its <code>OnInit()</code> function:</p>
  
  <pre><code> this._http.get(this._url+this.SNO+"&amp;"+this.randomno,{headers:headers})
     .subscribe(data =&gt; {this.list=data.json();
  </code></pre>
  
  <p>Now this page has a field to add new record. Once user adds the record, I am basically reloading the page using below code:</p>
  
  <p><code>this.navCtrl.setRoot(CommunicationPage</code></p>
  
  <p>I want to refresh the data without reloading the page, how do I do this?</p>
