Fixing AJAX Problem after calling success function .html()

after using this ajax and "replacing" tabulka class with another tabulkaSecond class AJAX on click is stop working!

$.ajax({
url:"mathupdateTabulka.php",
method:"POST",
data:{dateOdd:dateOdd, dateDoo:dateDoo},
success:function(data){
$(".tabulkaSecond").html(data);
}
});
$(".tabulka").css("display", "none");


here is mathupdateTabulka.php and I am not able to call class="material-icons-sharp delete-icon" anymore when I use above ajax...
<?php
require_once 'function.php';
if (isset($_POST['dateOdd'])) {

$dateOdd = $_POST['dateOdd'];
$dateDoo = $_POST['dateDoo'];

$SqliFirma = " SELECT Firma, NakladOd, NakladDo, Math FROM zoznamFirma WHERE Firma != '' AND Math != ''";

$FirmaResult = mysqli_query($conn, $SqliFirma) or die(mysqli_error());
while($row = mysqli_fetch_array($FirmaResult))
{
$FirmaArray[] = $row['Firma'];
$FirmaFullArray[] = $row['Firma'];
$NakladOdArray = $row['NakladOd'];
$NakladDoArray = $row['NakladDo'];
}
$FullArray = implode(', ', array_map(function($val){return sprintf("'%s'", $val);}, $FirmaArray));

$query = "SELECT * FROM fakturynaklad WHERE Firma IN ($FullArray) AND Prijate >= '".$NakladOdArray."' AND Prijate <= '".$NakladDoArray."' AND Stredisko != 'ViacStredisk'";
$result = mysqli_query($conn, $query);

if (mysqli_num_rows($result) > 0) {?>

<table>
<thead>
<tr>
<th>Firma</th>
<th>Stredisko</th>
<th>CisloFaktury</th>
<th>Prijate</th>
<th>Suma</th>
</tr>
</thead>
<tbody>
<?php
while ($row = mysqli_fetch_assoc($result)) {

$Firma = $row['Firma'];
$Stredisko = $row['Stredisko'];
$CisloFaktury = $row['CisloFaktury'];
$Prijate = $row['Prijate'];
$Suma = $row['Suma'];
$Id = $row['ID'];
$NazovObrazku = $row['NazovObrazku'];
$Obrazok = $row['Obrazok'];

?>

<tr>
<td><span class="material-icons-sharp delete-icon" data-id="<?php echo $Obrazok;?>" style="margin-right: 1rem; cursor: pointer;">search</span><?php echo $Firma; ?></td>
