not working in ng-repeat

[akashdeepshah]

I have used like the code below and it's not working.

 <div class="list card listinfo" ng-repeat="(key,dtls)  in ddetails.details">
  <h2 contenteditable="true" ng-model="dtls.title"></h2>
   <p contenteditable="true"  ng-model="dtls.subtitle"></p>
  </div>

I have also tried like this

   <div class="list card listinfo" ng-repeat="(key,dtls)  in ddetails.details">
      <h2 contenteditable="true" ng-model="ddetails.details[key].title"></h2>
       <p contenteditable="true"  ng-model="ddetails.details[key].subtitle"></p>
  </div>
