Попытка конвертировать https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_filter_table страницу с помощью IPython.display Но JavaScript не вызывается.

Попытка конвертировать https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_filter_table страницу с использованием IPython.display в Jupyter Notebook.Предоставив код, который я пробовал. 

    display(Javascript("""
        var input, filter, table, tr, td, i, txtValue;
        input = document.getElementById(\"myInput\");
        filter = input.value.toUpperCase();
        table = document.getElementById(\"myTable\");
        tr = table.getElementsByTagName(\"tr\");
        for (i = 0; i < tr.length; i++)
        {
            td = tr[i].getElementsByTagName(\"td\")[0];
            if (td)
            {
                txtValue = td.textContent || td.innerText;
                if (txtValue.toUpperCase().indexOf(filter) > -1) {
                    tr[i].style.display = \"\";
                } else
                {
                    tr[i].style.display = \"none\";
                }
            }
        }
