title: unable to bind value to ng-model of select with ng-repeat on button click
body: <p>I have TableObject as below </p>
  
  <pre><code>$scope.tableObject = [
      {
          'Column_Name' : 'Dummy 1',
          'Column_Cliass' : 'Valid'
      },
      {
          'Column_Name' : 'Dummy 2',
          'Column_Cliass' : 'Invalid'
      }
  ]
  </code></pre>
  
  <p>Now plotting select control using ng-repeat as below.</p>
  
  <pre><code>&lt;div class="row networkDataBR" ng-repeat="lTable in tableObject"&gt;
      &lt;select class="form-control" ng-model="lookupFile" ng-options="option as option.name for option in onlyFiles"&gt;
      &lt;/select&gt;   
  &lt;/div&gt;
  </code></pre>
  
  <p>It will make two Select Controls, Now on Button Click I want to assign value to one select control from Controller.</p>
  
  <pre><code>&lt;input class="btn btn-primary" type="button" ng-click="appendFile("Network")" value="Append" /&gt;
  
  $scope.appendFile = function(dataValue) {
      _.each($scope.tableObject, function (lTable) {
          if (lTable.Column_Name === "dummy") {
              $scope.lookupFile = dataValue;
          }
      });
  };
  </code></pre>
  
  <p>However, it applies to both the select control. So how to apply to single select?</p>
