title: pubnub isTyping status Ionic2
body: <p>I've implemented a chat using Ionic2 with pubnub, the thing is how can I implement the <code>isTyping</code> to show it on my <code>html</code>? I know I have to create a <code>state</code> on my user, but I don't know how to update it.</p>
  
  <p>My <a href="https://paste.ofcode.org/bAmiLj58T3WuCrKq9mPaSq" rel="nofollow noreferrer"><code>pubnub service</code></a> have differents methods, and I thought I could add a <code>PubNubEventType</code> that it's called <code>TYPING</code> but I don't know how to update it from my component (where I have the chat implemented)</p>
  
  <p>This is my <a href="https://paste.ofcode.org/35WaRsrMGmJ8hQDRgYiHREa" rel="nofollow noreferrer"><code>component</code></a>...</p>
  
  <p>Any ideas?</p>
