The below code works fine, independently. Meaning, if I come to the page and smash the like button it will function correctly and display the unlike button. However, if I immediately click the unlike button following that, nothing will happen. I will have to refresh the page and functionality will resume. Am I missing a crucial step here or is my logic flawed?
        $(document).ready(function(){
            var content = <?php echo $content['id']; ?>;
            user = <?php echo $user['id']; ?>;
            $('.like').on('click', function(e){
                e.preventDefault();
                $.ajax({
                    url: 'ajax.php',
                    type: 'post',
                    data: {
                        'content': content,
                        'user': user,
                        'like': 1
                    },
                    success: function(response){
                        $(".like").replaceWith( "<a href='#' class='btn btn-sm btn-danger rounded-pill unlike' data-id='<?php echo $content['id']; ?>'><i class='fas fa-skull'></i> Boo!</a>" );
                    }
                });
            });
            $('.unlike').on('click', function(e){
                e.preventDefault();
                $.ajax({
                    url: 'ajax.php',
                    type: 'post',
                    data: {
                        'content': content,
                        'user': user,
                        'unlike': 1
                    },
                    success: function(response){
                        $(".unlike").replaceWith( "<a href='#' class='btn btn-sm btn-success rounded-pill like' data-id='<?php echo $content['id']; ?>'><i class='fas fa-heart'></i> Woo!</a>" );
                    }
                });
            });
        });
