How to compare for two different objects inside ng-repeat

What is the best way to compare two different objects for equality inside of ng-repeat, why doesn't angular.equals work for me here:

<tr ng-repeat="row in ctrl.filteredItems" ng-class="{'active':angular.equals(row,ctrl.ngModel), 'focus': angular.equals(row,ctrl.focusedRow)}">
      <td ng-repeat="value in ctrl.sort(row) track by $index" class="text-center">
            {{value}}
      </td>
</tr>

I want to add the active class if the current row and the pre-selected row coming from the controller match.

Write a function in JS which will do angular.equals(obj1, obj2) and use this function to check is it active or not?

HTML

<tr ng-repeat="row in ctrl.filteredItems" ng-class="{'active': checkEqualiy(row, ctrl.ngModel), 'focus': checkEquality(row,ctrl.focusedRow)}">
  <td ng-repeat="value in ctrl.sort(row) track by $index" class="text-center">
        {{value}}
  </td>
</tr>

JS

$scope.checkEquality= function(param1, param2){
   return angular.equals(param1, param2)
}
