JQuery reset select2 dans modal

Question

J'ai essayé la manière comme ceci de réinitialiser select2 dans mon modal, mais cela ne fonctionne pas.

$(".payment-method").select2('data', null); 

<div class="modal-body"> 
        <form class="form-horizontal" id="category-form" enctype="multipart/form-data"> 
        {{ csrf_field() }} 
         <div class="col-xs-12 col-sm-6 col-md-6"> 
          <label>Payment Methods (Untuk kebutuhan tertentu)</label> 
          <div class="dropdown"> 
          <select class="form-control payment-method" name="paymentType" multiple="multiple" data-placeholder="Select the payment method"> 
           <option value="1">cash</option> 
           <option value="2">credit</option> 
           <option value="3">debit</option> 
          </select> 
          </div> 
         </div> 
         </div> 

       </form> 
       </div>
