Datatable not refreshing on ajax inside each loop - php

Question

Scenario :
I have a datatable which has checkbox on each row. When i try to select all checkbox and remove all selected data from datatable, it was not refreshing but the code works perfectly fine on the backend. But when i try to select all except 1 row (any of the row) it works fine...
phpaction :
$query = "
SELECT id ID, code Code, name Name, description Description FROM tablename WHERE active = 1 ORDER BY id ASC";
$res = mysqli_query($dbcon, $query);
if (mysqli_num_rows($res) > 0) {
$data = array();
$tbl = '';
while ($row = mysqli_fetch_assoc($res)) {
$data[] = $row;
}
echo json_encode($data);
} else {
echo json_encode('');
}
ajax:
$datatable.find('input[type="checkbox"]:checked').each(function() {
ID = $(this).attr("value").substr((($(this).attr("value")).length - 8) * -1);
remove(ID);
});
function remove(ID) {
requestAction = 'remove';
$.ajax({
url: 'phpaction.php',
method: 'post',
data: {
requestAction: requestAction,
ID: ID
},
success: function(data) {
list();
},
error: function(err) {
console.log(err);
}
});
}
