Google Wallet Generic Class (two-item row is not shown)

I followed the codelab for adding a new card to google wallet (of course I used the business profile of the company and the issuer id was not temporary).

As one of steps, I added one row with two items, in generic_class.js,but it is not shown in the final generated card

'classTemplateInfo': {
'cardTemplateOverride': {
  'cardRowTemplateInfos': [
    {
      'twoItems': {
        'startItem': {
          'firstValue': {
            'fields': [
              {
                'fieldPath': 'object.textModulesData["company"]',
              },
            ],
          },
        },
        'endItem': {
          'firstValue': {
            'fields': [
              {
                'fieldPath': 'object.textModulesData["badgeId"]',
              },
            ],
          },
        },
      },
    },
  ],
}

(of course, if I click on details, they are shown in the bottom, outside of the card).

Then I noticed that the final card of the codelab is also without the row!

So I want to add two or three rows to my generic_class like the pass builder, any idea?

I searched the web and asked wallet support team, no answer yet.

OMG, I found the solution! I wrongly updated the class :-| It should be like this:

  updatedClass['classTemplateInfo'] = {
    "cardTemplateOverride": {
      "cardRowTemplateInfos": [
        {
          "twoItems": {
            "startItem": {
              "firstValue": {
                "fields": [
                  {
                    "fieldPath": "object.textModulesData['company']"
                  }
                ]
              }
            },
            "endItem": {
              "firstValue": {
                "fields": [
                  {
                    "fieldPath": "object.textModulesData['badgeId']"
                  }
                ]
              }
            }
          }
        }
      ]
    }

};

I had written an extra 'classTemplateInfo': { under the updatedClass['classTemplateInfo'] = { and that's why it didn't work!
