Add custom fields upon user creation - wordpress

Question

I was trying to add custom fields using the hooks:
add_action( 'show_user_profile', 'extra_user_profile_fields' );
add_action( 'edit_user_profile', 'extra_user_profile_fields' );
and it perfectly fine but it only shows upon editing of users and not upon creating new users. How can I add custom fields upon creation? Can I also specify to only show this field depending on the selected user role?
Edit
Also tried the suggestion:
do_action( 'user_new_form', 'extra_user_profile_fields' );
But it doesn't seem to work

Add your custom fields using follows- hook to show it in add user section.
do_action( 'user_new_form', 'add-new-user' );
And the code snippet are as follows -
// Add extra custom data
function extra_user_profile_fields(){
?>
<h3>Extra User Profile data</h3>
<table class="form-table">
<tr>
<th><label for="company">Company Name</label></th>
<td>
<input type="text" class="regular-text" name="company_name" value="" id="company_name" /><br />
<span class="description">Add your company name.</span>
</td>
</tr>
</table>
<?php
}
add_action( "user_new_form", "extra_user_profile_fields" );
// Used to save extra custom data
function save_extra_user_profile_fields($user_id){
if(isset($_POST['company_name']))
update_user_meta($user_id, '_user_company', $_POST['company_name']);
}
add_action('user_register', 'save_extra_user_profile_fields');
And you can show or hide this fields for selected user role using scripts.
