重新加载表单中的字段时出现问题[关闭]

Question

I am having problems with a reloading fields in special with datepicker in a form.

The site is online on http://eskelak.eus/ and when I try to perform a search in the search form the first time is ok, but when I push reset button before, the datepicker fields is not restoring.

function the_search_form() {
global $wpdb;

$firstname = filter_input(INPUT_GET, 'first_name', FILTER_SANITIZE_STRING);
$lastname = filter_input(INPUT_GET, 'last_name', FILTER_SANITIZE_STRING);
$province = filter_input(INPUT_GET, 'province', FILTER_SANITIZE_STRING);
$locality = filter_input(INPUT_GET, 'locality', FILTER_SANITIZE_STRING);
$from = filter_input(INPUT_GET, 'from', FILTER_SANITIZE_STRING);
$to = filter_input(INPUT_GET, 'to', FILTER_SANITIZE_STRING);


if (!empty($locality) && isset($locality)) {
    $locality_row = $wpdb->get_row( $wpdb->prepare(
        'SELECT * FROM wp_eskelak_locality WHERE id = %s',
        $locality
    ) );
    $province = $locality_row->province;
}


$active = ' class="active"';
?>
<!-- START SEARCH FORM -->
<form method="get" action="/index.php" id="search">
    <?php $lang = get_language_for_link() ?>
    <?php if ($lang == '') : ?>
        <input type="hidden" name="page_id" value="370"/>
    <?php else : ?>
        <input type="hidden" name="page_id" value="372"/>
    <?php endif ?>

    </div>
    <div class="form-group">

            <?php _e('Reiniciar Filtro', 'eskelak')?>
        </button>
    </div>
</form>

<div class="clear"></div>
<!-- END SEARCH FORM -->
<?php}

That happens because the script that sets up the datepicker

<script src="data:text/javascript,(function(%24)%7B%24(%22.datepicker%22).datepicker(%7BshowButtonPanel%3Atrue%2CdateFormat%3A%22dd%2Fmm%2Fyy%22%7D)%3B%7D)(jQuery)%3B" type="text/javascript">(function($){$(".datepicker").datepicker({showButtonPanel:true,dateFormat:"dd/mm/yy"});})(jQuery);</script>

which in the home page is just after the form, is missing in the second page.
