I am looking for methods to debug the tempalte rendering after adding a record to the has many .

currently the template isnt updating with the recently added section, i even tried returning the card object again after submitting the section post

below is an example of the response

{
  "card": {
    "id": "2",
    "title": "MyCard",
    "left": 0,
    "top": 0,
    "user": "0",
    "tags": [
      "0"
    ],
    "sections": [
      "22469",
      "22471"
    ]
  },
  "section": {
    "id": "22471",
    "type": "Properties",
    "position": 1,
    "card": "2",
    "title": "Properties"
  }
}
