title: ng-model not working with select
body: <p>This might probably be a duplicate question but I am stuck while showing the default value from my data while binding another array to dropdown list. The list gets populated but the selected value which should show up after loading is not showing up.</p>
  
  <h2>This is my sample code:</h2>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div ng-app="app"&gt;
  &lt;div ng-controller="myCntrl"&gt;
    &lt;select class="form-control right" 
    ng-if="subscription.subscribedAddresses.ChannelType=='EMAIL'" 
    ng-model="subscription.subscribedAddresses.ChannelAddress" 
    ng-options="channel.ChannelAddress for channel in commInfo.emails track by channel.ChannelAddress" required&gt;
    &lt;/select&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>
  JS:</p>
  
  <hr>
  
  <pre><code>angular.module('app', [])
  .controller('myCntrl', ['$scope', function($scope) {
  $scope.commInfo = {
    "emails": [{
      "ChannelAddressId": 5000054652,
      "DeliveryChannel": "EMAIL",
      "ChannelType": null,
      "ChannelAddress": "ya_ajay@net.com"
    }, {
      "ChannelAddressId": 5000075277,
      "DeliveryChannel": "EMAIL",
      "ChannelType": null,
      "ChannelAddress": "yad_ay@ts.com"
    }, {
      "ChannelAddressId": 5000075278,
      "DeliveryChannel": "EMAIL",
      "ChannelType": null,
      "ChannelAddress": "yadav_aaj@gmail.com"
    }, {
      "ChannelAddressId": 5000075279,
      "DeliveryChannel": "EMAIL",
      "ChannelType": "UNKNOWN",
      "ChannelAddress": "test_ay@mail.com"
    }],
    "phones": [{
      "ChannelAddressId": 5000075390,
      "DeliveryChannel": "PHON",
      "ChannelType": "UNKNOWN",
      "ChannelAddress": "4561237895"
    }, {
      "ChannelAddressId": 5000075397,
      "DeliveryChannel": "PHON",
      "ChannelType": "UNKNOWN",
      "ChannelAddress": "7894561236"
    }]
  };
  $scope.subscription = {"serviceName":"RAM Month","subscribedAddresses":{"ChannelAddress":"yad_ajay@ts.com","ChannelType":"EMAIL"}};
  }]);
