Checkbox which is getting checked in the summernote editor, not reflecting in the code elements

I have created the custom button, on pressing this button, I have included the checkbox by using this code,
 context.invoke('editor.pasteHTML', '<input type="checkbox" class="note-editor-checkbox"/>');

By on clicking, the code should be changed into <<  #input type="checkbox" checked="checked" class="note-editor-checkbox"/>>, but that was not happened, no change in the code.
