清除textfield黑莓

Question

如何清除黑莓中的TextField？这里的QML：

Container { 
         horizontalAlignment: HorizontalAlignment.Center 
         verticalAlignment: VerticalAlignment.Bottom 
         leftPadding: 75 
         rightPadding: leftPadding 
         bottomPadding: 40 

        TextField { 
         id: tfComment 
         hintText: qsTr("add comment") 
         inputMode: TextFieldInputMode.Text 
         input { 
          submitKey: SubmitKey.Submit 
          onSubmitted: { 
           cppObj.onCommentSubmitClicked(tfComment.text, ""); 
           lComment.text = tfComment.text; 
          } 
         } 
        } 
       } 

Container { 
         horizontalAlignment: HorizontalAlignment.Center 
         verticalAlignment: VerticalAlignment.Bottom 
         bottomPadding: 200 
         leftPadding: 20 
         rightPadding: leftPadding 

         Label { 
          id: lComment 
          verticalAlignment: VerticalAlignment.Bottom 
          horizontalAlignment: HorizontalAlignment.Center 
          text: cppObj.desc 
         } 
        } 

我要清除的数据输入到TextField这样就会有空间，我发表评论另一个。我怎么做？
