WP is not using the select custom template.php that its selected for a page

I created a childtheme: Fisio

Inside I have: page-team.php with the name:

<?php
/*
Template Name: Page - Team
*/
?>
<?php get_header(); ?>
<script>alert('its the team page')</script> 

And in the wp-admin I selected it for the page: Team

The problem is that any changes I make to page-team.php are not affected. In fact, the alert is never executed.

What am I missing?

PD: Is there a way to know wich was the template used having a look to the source code? I can’t find this

-EDIT-

forgot to mention that team is listing a custom post_type: team, here is the declaration in functions.php

<?php
/**
 * Custom Post type register framework
 */
include(get_stylesheet_directory(). '/inc/acpt/init.php');
add_action('init', 'makethem');
function makethem() {
    $args = array(
        'supports' => array( 'title', 'editor', 'page-attributes', 'thumbnail', 'excerpt'  ),
        'hierarchical' => true,
    );

    $team = new post_type('team','team', false,  $args );

}

/**
 * Initialize the metabox class
 */
add_action( 'init', 'be_initialize_team_meta_boxes', 9999 );
function be_initialize_team_meta_boxes() {
    if ( !class_exists( 'team_Meta_Box' ) ) {
        require_once( get_stylesheet_directory(). '/inc/metaboxes/fisio-metaboxes.php' );
        require_once( get_stylesheet_directory(). '/inc/metaboxes/init.php' );

    }
}
?>
