I have a js code on the page, inside this code I need to make some part of the text editable, but I try to insert the Bitrix code there, it does not recognize it, how can I do this? Sample code

<script type="text/javascript">
      var newYear = new Date(); 
    newYear = new Date(newYear.getFullYear() + 1, 1 - 2, 1); 
  $('#defaultCountdown').countdown({until: 'ТУТ ТЕКСТ СДЕЛАТЬ РЕДАКТИРУЕМЫМ', format: 'HMS'});
