Shortcode does not render custom form, rather showing its name as text

Hi,
I have started learning WordPress recently. I am trying to create a custom form for users to post data using a custom post type which I have created without plugin. For this I have created a custom plugin and activated it from admin. The plugin which looks like this:

<?php
/*
Plugin Name: Custom frontend entry form
Description: Custom frontend entry form for publishing trip reports by users
Version: 1.0
Author: Subrata Sarkar
*/

/* Register Custom Post Type */
function trip_report_init() {
    //Set up labels
    $labels = array(
        'name' => 'Trip Report',
        'singular_name' => 'Trip Report',
        'add_new' => 'Create New Report',
        'add_new_item' => 'Create New Report',
        'edit_item' => 'Edit Trip Report',
        'new_item' => 'New Trip Report',
        'all_items' => 'All Trip Reports',
        'view_item' => 'View Trip Report',
        'search_items' => 'Search Trip Reports',
        'not_found' => 'No Trip Report Found',
        'not_found_in_trash' => 'No Trip Report found in Trash',
        'parent_item_colon' => '',
        'menu_name' => 'Trip Reports'
    );

    //register_post_type
    $args = array(
        'labels' => $labels,
        'public' => true,
        'has_archive' => true,
        'show_ui' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'rewrite' => array('slug' => 'trip-reports'),
        'query_var' => true,
        'menu_icon' => 'dashicon-normalize',
        'supports' => array(
            'title',
            'editor',
            'excerpt',
            'comments',
            'author',
            'thumbnail',
            'page-attributes'
        )
    );

    register_post_type('trip_report', $args);

    //register taxonomy
    register_taxonomy('report_category', 'trip_report', array(
        'hierarchical' => true,
        'label' => 'Report Category',
        'query_var' => true,
        'rewrite' => array('slug' => 'report-category')
    ));

    //echo 'Trip report entry form';
}
add_action('init', 'trip_report_init');
/* Ends registration */

/* Build the form */
function trip_report_entry_form() { ?>
    <form id="trip-report-entryform" name="trip-report-entryform" method="post" action="">
        <div class="row">
            <div class="col-md-12">
                Report title <i class="red-text">*</i>
                <input type="text" id="txtTitle" name="txtTitle" class="form-control" maxmaxlenght="30" required />
            </div>
            <div class="clearfix"></div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <input type="submit" value="Submit" class="btn btn-primary text-small" />
            </div>
            <div class="clearfix"></div>
        </div>
    </form>
<?php }
/* Ends form */

add_shortcode('new_trip_report', 'trip_report_entry_form');

//if ( shortcode_exists( 'new_trip_report' ) ) { echo "The shortcode exists";}

?>

But when I add the shortcode in a page content editor, the page does not render the form rather it only displays the name of the shortcode as text.
What I am doing wrong?
