self.parent reference not updating

[dwissmann]

Hi - first, I am really excited to use django-unicorn in a production use-case. But before I do, I need some assistance.

I have a simple model that has a self-referencing foreign key to for a parent-child relationship. A parent can have multiple children and a child can only have one parent (a tree structure). See here:

class Tree(models.Model):
    BRANCH_TYPE = {
        "B": "Branch",
        "L": "Leaf",
        "E": "External Choice",
    }
    title = models.CharField(max_length=255)
    desc = models.CharField(max_length=1024)
    type = models.CharField(max_length=1, choices=BRANCH_TYPE)
    external = models.CharField(max_length=1024)
    parent = models.ForeignKey('self', models.SET_NULL, null=True, blank=True, parent_link='children')
    
    def __str__(self):
        return self.title

I created a component and two child components - parent title and a list of it's children (loop) and another for adding a new child:

{% load unicorn %}
<div>
    <div class="prompt" unicorn:click="walk_back()">{{ prompt_title }}</div>
    <hr>
    <div class="childrenoptions">
    {% for option in child_options %}
        {% unicorn 'tree-walk-options' option=option key=option.id %}
    {% endfor %}
    </div>      
    {% unicorn 'tree-add-option' key=option.id %}
</div>

When I "walk the tree" (click on child who becomes the new parent) the reference in the child self.parent does not update correctly.

Is this a bug?
