Custom comparator is not working

[mdsahib]

I am trying to pass a custom comparator for a column but it is not getting called.

After researching the source code, I found that the comparator function is not passed while sorting the data.

      var clientSorts = [];
      for(var i=0, len=sorts.length; i < len; i++) {
        var c = sorts[i];
        if(c.comparator !== false){
          var dir = c.sort === 'asc' ? '' : '-';
          clientSorts.push(dir + c.prop);
        }
      }

      if(clientSorts.length){
        // todo: more ideal to just resort vs splice and repush
        // but wasn't responding to this change ...
        var sortedValues = this.$filter('orderBy')(this.rows, clientSorts);
        this.rows.splice(0, this.rows.length);
        this.rows.push(...sortedValues);
      }
