title: Select tag not returning input data in correct form (Angular)
body: <p>Using my json file, I'm making select type of questions on my web app. 
  The code I have for my select tag is like following: </p>
  
  <pre><code>&lt;div class="form-group" ng-class="{ 'has-error': form.$submitted &amp;&amp; form[field.id].$invalid }" ng-if="field.type === 'select'"&gt;
     &lt;label for="{{field.id}}"&gt;{{field.title}}&lt;/label&gt;
     &lt;br&gt;
     &lt;select ng-model="formData[field.id]" ng-value="{{value.title.id}}" ng-options="value as value.title for value in field.values"&gt;
     &lt;option disabled selected value&gt; -- select an option -- &lt;/option&gt;&lt;/select&gt;
     &lt;p class="form-group-note" ng-if="field.info" ng-bind="field.info"&gt;&lt;/p&gt;
     &lt;div ng-show="form.$submitted" ng-cloack&gt;
        &lt;span class="help-block" ng-show="form['{{field.id}}'].$error.required" ng-if="field.validations.required"&gt;Please enter a value, this field is required&lt;/span&gt;
     &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I have a json file like following:</p>
  
  <pre><code>{
    "groups": [
     {
       "id": "10_8_group",
       "title": "Existence",
       "index": 60,
       "part": 10,
       "sections": [
         {
           "id": "10_8_section",
           "title": "Existence",
           "fields": [
              {
                 "id": "10_8_labor_organization",
                 "title": "8. Does it exist?",
                 "info": "Always select \"No\"",
                 "type": "select",
                 "size": {
                     "width": 100,
                     "height": 1
                 },
                 "values": [
                     {
                         "id": 1,
                         "title": "Yes"
                     },
                     {
                         "id": 2,
                         "title": "No. If no, proceed to Part 9. and type or print your explanation."
                     }
                 ]
              }
           ]
         }
       ]
     }
    ]
  }
  </code></pre>
  
  <p>when the data is being saved in localStorage(Angular's frontend model), it saves the data as <code>"10_8_labor_organization":{"id":1,"title":"Yes"}}</code></p>
  
  <p>However, I would like to save this as</p>
  
  <pre><code>"10_8_labor_organization":"Yes"
  </code></pre>
  
  <p>How can I accomplish this??</p>
