Impossible to change input value with javascript-CodePudding

This code actually works on dev environnement but doesn't work in google app script sidebar for google spreadsheet. What's the problem ?

    <input id="date1" name="date" type="date" onchange="changedate()">
    <input id="date2">

<script>

  function changedate() {
    var dateVar = document.getElementById("date1").value;
    document.getElementById("date2").value = dateVar;

  }   
  
</script>

This works for me as a dialog:

function launchALittleDialog() {
  let html = '<input id="date1" name="date" type="date" onchange="changedate()"><input id="date2"><script>function changedate() {var dateVar = document.getElementById("date1").value;document.getElementById("date2").value=dateVar;}</script>';
  SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html),'Title')
}
