title: Cordova iOS plugin doesn't work until the app changes focus
body: <p>I am using this plugin <a href="https://github.com/EddyVerbruggen/cordova-plugin-touch-id" rel="nofollow noreferrer">https://github.com/EddyVerbruggen/cordova-plugin-touch-id</a> on my app. When I call the methods, the callbacks are not called until I focus out the app and bring it back in focus. I have seen this same problem with two different plugins. Is this a cordova ios bug or is there some thing that I need to do?</p>
  
  <pre><code>window.plugins.touchid.isAvailable(
    function(type) {alert(type)}, // this will not be called until I focus out and back in the app
    function(msg) {alert('not available, message: ' + msg)} // this will not be called until I focus out and back in the app
  );
  </code></pre>
  
  <p>Your help is appreciated!</p>
