Filter list dict in JsonField Postgres

Hi, I have this model:

class ItemCampaign(models.Model):

   campaign = models.ForeignKey(

       Campaign, related_name="itemscampaign", verbose_name="Item campaña"

   )

   data = JSONField(default=dict)

   def __str__(self):

       return self.campaign.name 

With a record with this data: 

[{'number': '1160188479', 'id': 0, 'content': 'hello', 'processed': True}, {'number': '1160188479', 'id': 1, 'content': 'hello', 'processed': False}, {'number': '1160188479', 'id': 2,'content': 'hello', 'processed': False}, {'number': '1162341721', 'id': 3, 'content': 'hello', 'processed': False}, {'number': '1162341721', 'id': 4, 'content': 'hello', 'processed':False}, {'number': '1162341721', 'id': 5, 'content': 'hello', 'processed': False}]

I want filter this list dict, like this:

c.itemscampaign.filter(data__processed=True)

But not work. That does not give me back anything.

The content type of data is:

>>> type(c.itemscampaign.all()[0].data)
<class 'list'>

I understand that it has to be a dict, but how can I insert many dictionaries in the field, as I have in my data if it is not in a list?

Thanks!
