  <div style="display: flex; justify-content: space-around; margin: 5px auto auto auto;">
   <button data-xdh-onevent="Submit">Submit</button>
   <button data-xdh-onevent="Clear">Clear</button>

sub acConnect {
    my ($hello, $dom) = @_;


sub acSubmit {
    my ($hello, $dom) = @_;

    $dom->alert("Hello, " . $dom->getContent("input") . "!");

sub acClear {
    my ($hello, $dom) = @_;

    if ( $dom->confirm("Are you sure?") ) {
        $dom->setContent("input", "");
