Firebase - How to update many children and not delete others in AngularFire

Question

I want to use update () for firebase ref to update many children in one operation. To do this, I passed an object with the values ​​that need to be changed.

Here is the output of console.log (angular.toJson (change, 1))

{
  "10": {
    "otherRubies": 30
  },
  "11": {
    "otherRubies": 30
  }
} 

In the beginning I have:

Then I do:

var refUsers = new Firebase(FBURL).child('users/');
refUsers.update(change);

So I want to have:

but instead I get:

Is there any way to do this?

This is an example of a recursive update:

function updateRecursively(path, value) {
  for (let key in value) {
    if (value[key] instanceof Object) {
      updateRecursively(`${path}/${key}`, value[key]);
    } else {
      firebase.database().ref(`${path}/${key}`).set(value[key]);
    }
  }
}

Using:

updateRecursively('users', {
  "10": {
    "otherRubies": 30
  },
  "11": {
    "otherRubies": 30
  }
})
