Braintree Dropin user interface does not work with Ionic Framework if force update

Question

I encounter very strange behavior with the Braintree dropin user interface in the Ionic framework.

So, I use the solution: It is not possible to create a Braintree client token with a client ID to create logic for the first time and return the client.

$http({
          method: 'POST',
          url: 'http://localhost:3000/api/v1/token',
          data: {
            customerId: braintreeReturnCustomerId
          }
        })

How I went to customerId in my customer view. On my nodejs server, I have logic to check if customerId is undefined. If it is undefined, this is the first client. If customerId matters, he is a return customer. Very straightforward:

app.post('/api/v1/token', jsonParser, function (request, response) {

var customerId = request.body.customerId;

 if (customerId == undefined) {

   gateway.clientToken.generate({}, function (err, res) {
    if (err) throw err;
     response.json({
      "client_token": res.clientToken
    });
  });
  } else {
    console.log ("using exsiting customer!");
    gateway.clientToken.generate({
        customerId: customerId
    }, function (err, res) {
    if (err) throw err;
    response.json({
      "client_token": res.clientToken
     });
   });
 }


 });
