Align check boxes on the same row using bootstrap 3

I am using bootstrap 3 modal, where i am generating checkboxes dynamically . It works fine. I need to align the checkboxes on the same row. So i have used

 <div class="row" >                           
     <div   ng-repeat="item in selectedFields">
          <md-checkbox ng-model="checkbox"  class="col-xs-12" aria-label={{item.name}}>
          {{item.name}}
     </md-checkbox>
     </div>
  </div>
