How to create $http delete req in angularjs

All i want is to delete a row of a table by clicking a button. I am diong something like this

  .controller('removeInput' , function($scope, $http) {
    $scope.remove = function(index){
      var inputId = {'inputId': $scope.inputId};
      $http.delete(baseUrl + '/input/' ,inputId, _auth)
      .success(function (){
        console.log('deleted');
      }).error(function(err){
        console.log(err);
      });
    };
  });

and in html its something like this

<tbody ng-controller = "input">
 <tr ng-repeat = "inputs in inputData">
  <td ng-model = "inputId">{{inputs.inputId}}</td>
  <td><img ng-src = "{{inputs.thumbnailUrl}}"/></td>
  <td>{{inputs.filename}}</td>
  <td></td>
  <td>{{inputs.updatedAt.date}}</td>
  <td ng-controller = "removeInput">
   <a class = "btn btn-option" ng-click = "remove(index)">
    <span class = "glyphicon glyphicon-remove"></span>
   </a>
  </td>
 </tr>
</tbody>
