Visual Composer: Custom Shortcode Not Working

Question

The following is the shortcode I created in functions.php:

function echo_first_name() {
    echo $_GET['first_name'];
}
add_shortcode( 'first_name', 'echo_first_name' );

And I'm entering the following into my Visual Composer editor:

['first_name']

This produces no result, even when using the Visual Composer shortcode mapper.

Does anybody know why this isn't working? Do I have to register it as another type of shortcode for Visual Composer to be able to access it?

For Create Short code

if you want to add short code in editor then Used return instead of echo

function echo_first_name() {
    return $_GET['first_name'];
}
add_shortcode( 'first_name', 'echo_first_name' );

Used Short Code Like

[first_name] 

If you want to pass the value In shortcode

function echo_first_name( $atts ) {
    $a = shortcode_atts( array(
        'firstname' => '',
    ), $atts );

    return "First Name= {$a['firstname']}";
}
add_shortcode( 'first_name', 'echo_first_name' );

Used Short Code Like

[first_name firstname="test"]
