how to localize the number of wordpress post views?

I want to display post view in localize number. I add these function in function.php to do so

function make_bangla_number($str)
{
    $engNumber = array(1,2,3,4,5,6,7,8,9,0);
    $bangNumber = array('১','২','৩','৪','৫','৬','৭','৮','৯','০');
    $converted = str_replace($engNumber, $bangNumber, $str);

    return $converted;
}

add_filter( 'the_views', 'make_bangla_number' );

But I am unable to show the number in localize. Whenever i call the_views it shows the english number. Any idea how to show the post view number in localize language?

For further info here is my post view function:

// function to count post views.
function setPostViews($postID) {
    $count_key = 'views';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}
// function to display number of post views.
function the_views($postID){
    $count_key = 'views';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return "0 View";
    }
    return $count.' বার';
}
