My pagination doesnt work in wordpress custom theme - php

Question

I am using pagination_bar from function.php. I implemented that in custom page called page-blog.php. I restriced pages to only 2 per page and i have 3 blog posts. After I put pagination_bar() function it shows me fatal error.
I saw some soluton already here but none of them helps. I have tried doing some offset.
function.php
function pagination_bar() {
global $wp_query;
$total_pages = $wp_query->max_num_pages;
if ($total_pages > 1){
$current_page = max(1, get_query_var('paged'));
echo paginate_links(array(
'base' => get_pagenum_link(1) . '%_%',
'format' => 'page/%#%',
'current' => $current_page,
'total' => $total_pages,
'prev_text' => '<i class="fa fa-angle-left"></i>',
'next_text' => '<i class="fa fa-angle-right"></i>'
));
}
}
page-blog.php
<div class="col-xl-8 col-md-12 col-lg-8 col-sm-12 col-xs-12 md-blog-posts">
<?php
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
$homePagePosts = new WP_Query(array(
'posts_per_page' => '2',
'post_type' => 'post',
'has_archive' => true,
'post_status' => 'publish',
'order' => 'DESC',
'paged' => $paged,
));
if($homePagePosts->have_posts()) :
while($homePagePosts->have_posts()) :
$homePagePosts->the_post(); ?>
<div class="col-xs-12 col-md-12 col-lg-12 md-blog-blog">
<div class="md-blog-img">
<div class="img-container">
<div class="positioning">
<span class="md-blogdate-number"><?php the_time('F d, Y.'); ?></span>
<h4 class="md-blog-title"><?php echo get_the_title() ?></h4>

</div>
<div class="md-blog-img"><?php the_post_thumbnail() ?></div>
</div>
</div>
</div>
<?php endwhile; ?>
<?php else : ?>
<h1>There is no posts at this moment</h1>
<?php endif; ?>
<div class="md-pagination-holder" style="background: #333; width:50px; height: 50px; color: #fff;">
<?php paginate_bar(); ?>
</div>
</div>
Also you can see the website here - > http://prodenvermovers.wpupkeep.org/blog/
I get fatal error.
EDIT : http://prntscr.com/oij1dr
I chaned paginate_bar to pagination_bar as function is actually called but i get error above when i refresh the page.

Try this to see if you can get the page to work. In this example it just uses the built in WP hooks to generate pagination links. Also, by "still not working" do you mean you are still getting the error, or just not seeing the pagination?
<div class="col-xl-8 col-md-12 col-lg-8 col-sm-12 col-xs-12 md-blog-posts">
<?php
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
$homePagePosts = new WP_Query(array(
'posts_per_page' => '2',
'post_type' => 'post',
'has_archive' => true,
'post_status' => 'publish',
'order' => 'DESC',
'paged' => $paged,
));
if($homePagePosts->have_posts()) :
while($homePagePosts->have_posts()) :
$homePagePosts->the_post(); ?>
<div class="col-xs-12 col-md-12 col-lg-12 md-blog-blog">
<div class="md-blog-img">
<div class="img-container">
