I am trying to call a function inside a class, but somehow the function is not getting fired. When hooking into the same hook and just logging a string, the string gets logged. So the hook should work.

HTML calling the Function

                     <div class="wrap">
                        <h2>Update Category</h2>

                        <form method="post" action="<?php echo plugins_url('accounting.php', __FILE__); ?>">
                            <input type="hidden" name="action" value="update_category">
                            <input type="hidden" name="action" value="<?php echo htmlspecialchars($_GET["ID"]); ?>">

                            <input type="text" name="category" placeholder="Category Name" value="<?php echo $category['category']; ?>">

                            <input type="text" name="description" placeholder="Category Description" value="<?php echo $category['description']; ?>">

                            <input type="submit" value="Update Category" class="button button-primary">

Create Instance of Class and initializing Hooks

if (class_exists('AccountingTool')) {
    $accountingTool = new AccountingTool();

add_action( 'admin_post_create_category', array($accountingTool, 'createCategory'));
add_action( 'admin_post_create_category', error_log("called"));


class AccountingTool {

    function __construct() {
        global $wpdb;
        $this->wpdb = $wpdb;
        $this->categoriesTableName = $this->wpdb->prefix . 'categories';

    function createCategory() {
        error_log("called 2");
        $category = $_POST['category'];
        $description = $_POST['description'];
        $res = $this->wpdb->insert($this->categoriesTableName, array(
            'ID' => NULL,
            'category' => $category,
            'description' => $description
        wp_redirect('/wp-admin/admin.php?page=category&ID=' . $this->wpdb->insert_id);
        error_log(var_export($_POST) . ", " . var_export($res));

Logs As seen below the string gets logged, but nothing afterwards.
