title: ng-repeat not bind ng-model array of objects
body: <p>I'm try to bind array of objects to html. But when I changed input value, model not changed. What i'm doing wrong?</p>
  
  <p>Sorry, this is very simple case, but i'm confused.</p>
  
  <p>My html:</p>
  
  <pre><code> &lt;div ng-app="myApp" ng-controller="myCtrl"&gt;
              &lt;table class="price-table"&gt;
                  &lt;tbody&gt;
                  &lt;tr ng-repeat="item in prices track by $index"&gt;
                      &lt;td&gt;&lt;span&gt;{{item.country_code}}&lt;/span&gt;&lt;/td&gt;
                      &lt;td&gt;&lt;input ng-value="prices[$index].price" ng-input="item.price = item.price" ng-disabled="!item.editMode" type="text"/&gt;&lt;/td&gt;
                      &lt;td&gt;&lt;button class="btn price-table-btn" ng-click="item.editMode = !item.editMode" ng-disabled="item.noEdit"&gt;&amp;#9998;&lt;/button&gt;&lt;/td&gt;
                      &lt;td&gt;&lt;button class="btn price-table-btn" ng-click="savePrice($index, item)" ng-disabled="!item.editMode"&gt;&amp;#10003;&lt;/button&gt;&lt;/td&gt;
                      &lt;td&gt;&lt;button class="btn price-table-btn" ng-click="removePrice($index, item)" ng-disabled="!item.editMode"&gt;&amp;times;&lt;/button&gt;&lt;/td&gt;
                  &lt;/tr&gt;
                  &lt;/tbody&gt;
              &lt;/table&gt;
       &lt;div&gt;
              {{prices}}
          &lt;/div&gt;
          &lt;/div&gt;
  </code></pre>
  
  <p>My code:</p>
  
  <pre><code>angular.module('myApp', []);
  
  angular.module('myApp')
  .controller('myCtrl', function($scope) {
      $scope.prices = [{"country_code":"00","price":"12.00","editMode":false,"noEdit":false},{"country_code":"01","price":"1.00","editMode":false,"noEdit":false},{"country_code":"AU","price":"8.00","editMode":false,"noEdit":false},{"country_code":"CA","price":"5.00","editMode":false,"noEdit":false},{"country_code":"GB","price":"10.00","editMode":false,"noEdit":false},{"country_code":"UK","price":"10.00","editMode":false,"noEdit":false},{"country_code":"US","price":"3.00","editMode":false,"noEdit":false}];
  });
  </code></pre>
