Unable to edit form field

Description

I followed the instructions to get a basic example working.
The field is editable in the admin interface but is not editable from within a ModelForm. A large textarea field is displayed in the HTML form but no data is shown or split.

What I Did

forms.py

class DataTestForm(ModelForm):
    class Meta:
        model = DataTest
        exclude = ["slug"]
        widgets = {"eeg": JSONEditorWidget}

models.py

def facilities_imaging():
    return {"nonessions": 0, "esthourspermonth": 0}

class DataTest(Model):
    eeg = JSONField(blank=True, null=True, default=facilities_imaging)    # also tried without a default

form.html

# tried all separately
{{ form.eeg|as_crispy_field }}
{{ form.as_p }}

page source (eeg form field)

    <div id="div_id_eeg" class="form-group">
        
            <label for="id_eeg" class="">
                Eeg
            </label>
                <div class="">
                    <div style="height:500px;width:90%;display:inline-block;" class="jsoneditorwidget form-control" id="id_eeg"></div>
​
<textarea id="id_eeg_textarea" name="eeg" required="" style="display: none">{&quot;nonessions&quot;: 0, &quot;esthourspermonth&quot;: 0}</textarea>    # removing style shows the raw json
​
<script>
    (function() {
        var container = document.getElementById("id_eeg");
        var textarea = document.getElementById("id_eeg_textarea");
​
        var options = {"modes": ["text", "code", "tree", "form", "view"], "mode": "code", "search": true};    # tried changing modes
        options.onChange = function () {
            var json = editor.get();
            textarea.value=JSON.stringify(json);
        }
​
        var editor = new JSONEditor(container, options);
        var json = {"nonessions": 0, "esthourspermonth": 0};
        editor.set(json);
    })();
</script><input type="hidden" name="initial-eeg" value="{&quot;nonessions&quot;: 0, &quot;esthourspermonth&quot;: 0}" id="initial-id_eeg">
                </div>
    </div>

This widget is only for the admin, for now.
