title: Call not working in android using cordova, grabbing contacts from phone
body: <p>I want to call a phone number from clicking on a link, but the contact should be retrieved from phone.
   So I implemented a code for this. But tel is opening dialer, but my retrieved contact number is missing. Any suggestion?</p>

          options.multiple=true;      // return multiple results

          alert('onError!');
