Custom Validation

I’m trying to create a custom validation but it’s not working this is my code:

add_filter( 'wpcf7_validate_text', 'your_validation_filter_func', 10, 2 );
add_filter( 'wpcf7_validate_text*', 'your_validation_filter_func', 10, 2 );

function your_validation_filter_func( $result, $tag ) {
    $type = $tag['type'];
    $name = $tag['name'];

    if ( 'cedula' == $name ) {
        $the_value = $_POST[$name];

        if ( !preg_match("/^(V|E|J)-[0-9]+$/", $the_value) ) {;
            $result['valid'] = false;
            $result['reason'][$name] = "Error message here";
        }
    }

    return $result;
}

Any ideas?
