Steps to reproduce:

1. Adding CInput('radio) in widget.view.php as follows.

   <?php
         // operation mode
         $coolLabel = new CLabel('Cool mode', 'coolLabel');
         $coolRadio = new CInput('radio', 'opMode', 'coolRadio');
         $coolRadio->setId('coolRadio');
         $dryLabel  = new CLabel('Dry mode', 'dryLabel');
         $dryRadio  = new CInput('radio', 'opMode', 'dryRadio');
         $dryRadio->setId('dryRadio');
         $opModeDiv = new CDiv([$coolLabel, $coolRadio, $dryLabel, $dryRadio]);
   
         // widgetView
         $widgetView = new CWidgetView($data);
         $widgetView->addItem($opModeDiv);
         $widgetView->show();
   

2. Setting check status of dryRadio in class.widget.js as follows.

   class WidgetAirConditioner  extends CWidget {
       onInitialize() {
       }
       
       onResize() {
       }
   
       processUpdateResponse(response) {
           super.processUpdateResponse(response);
       }
       
       promiseReady() {
           return super.promiseReady();
       } 
       
       setContents(response) {
           super.setContents(response);
           const coolRadio = document.getElementsByName("coolRadio"); 
           if (coolRadio) {
               console.log("coolRadio.checked = true");
               coolRadio.checked = true;
           }
       }
       
       onClearContents() {
       }
   }
   

1. "coolRadio.checked = true" log messages has been printed on web browser. But check status of coolRadio is not set.

Result:

1. "coolRadio.checked = true" log messages has been printed on web browser. But check status of coolRadio is not set.

Expected:

1. "coolRadio.checked = true" log messages has been printed on web browser. And check status of coolRadio is set.
