site hacked, code lost

My site was hacked and somehow code on my Events Calendar table page was corrupted.
Can someone help me to get the code complete again? I had a table that displayed all upcoming events with a search button. After the hack the table is converted into static HTML and I think some JAVAscript is missing. I tried using previous versions but they all are corrupted.
This is the code that is left:

<div class="em-search-wrapper">
	<div class="em-events-search em-search css-search has-search-term has-search-main no-advanced advanced-visible">
		<form action="https://www.grotetrek.nl/" method="post" class="em-events-search-form em-search-form">
		<div class="em-search-main">
			<!-- START General Search -->
			<div class="em-search-text em-search-field">
				EM.search_term_placeholder = 'Zoeken';
				<label>
					<span class="screen-reader-text">Zoeken</span>
				</label>
			</div>
			<!-- END General Search --> <button type="submit" class="em-search-submit loading">
			<!--[if IE 7]><span><![endif]-->
			<img src="https://www.grotetrek.nl/wp-content/plugins/events-manager/includes/images/search-mag.png" alt="Zoeken" />
			<!--[if IE 7]></span><![endif]-->
			</button>
		</div>
		</form>
	</div>
</div>

<div class='css-events-list'>
	<table cellpadding="0" cellspacing="0" class="events-table">
	<thead>
	<tr>
		<th class="event-time" width="150">Datum</th>
		<th class="event-time" width="150">Tijd</th>
		<th class="event-description" width="*">Evenement</th>
	</tr>
	</thead>
	<tbody>
	<tr>
		<td>09/04/2017</td>
		<td>13:00 - 17:00</td>
		<td><a href="https://www.grotetrek.nl/events/koopzondag-7/">Koopzondag</a></td>
	</tr>
	</tbody>
	</table>
</div>
