showcase how on-change attribute parsing can help with updating the relevant objects on scope. Looking at it now, maybe instad of parsing on-change, we could change it to ng-change to align the name with angular.

example.html

 <div ng-controller="langsCtrl">
   <tr ng-repeat="lang in langsList">
      <td>{{$index}}</td>
      <td>
          <div class="ade-editable" ade-text='{"className":"inputInTable"}'
               ng-model="lang.lang_code" on-change='update(lang)'>{{lang.lang_code}}</div>
      </td>
      <td>
          <div class="ade-editable" ade-text='{"className":"inputInTable"}'
               ng-model="lang.alt" on-change='update(lang)'>{{lang.alt}}</div>
      </td>
      <td><div class="ade-editable" ade-text='{"className":"inputInTable"}'
               ng-model="lang.icon" on-change='update(lang)'>{{lang.icon}}</div></td>
      <td><input ng-model="lang.enabled" type="checkbox" ng-change="update(lang)"></td>
      <td>
          <i class="icon-remove" ng-click="delete(lang, $index)" ></i>
      </td>
  </tr>
</div>

<script>
  function langsCtrl($scope){
    $scope.update = function (lang) {
           //put updated lang to server
    };
  }
</script>
