Using an array inside array - angularjs

Question

I'm trying to generate a form which will have multiple vehicles and each vehicle should have multiple people inside it.
I tried to do it by using an array inside another array. But for some obscure reasons it's not working.
This is what I want:

This is what I have (so far):
Form:
[
{
"key": "vehicles",
"items": [
"['vehicles'][]['plate-number']",
"['vehicles'][]['color']",
{
"key": "people",
"items": [
"['vehicles'][]['people'][]['name']"
]
}
]
}
]
Schema:
{
"type": "object",
"properties": {
"vehicles": {
"type": "array",
"items": {
"type": "object",
"properties": {
"plate-number": {
"title": "Plate number",
"type": "string"
},
"color": {
"title": "Color",
"type": "string"
},
"people": {
"type": "array",
"items": {
"type": "object",
"properties": {
"title": {
"type": "string",
"enum": ["dr","jr","sir","mrs","mr","NaN","dj"]
},
"name": {
"title": "Name",
"type": "string"
}
}
}
}
}
}
}
}
}
Edit:
stefankmitph's answer solvers my problem. Thank you!
But something weird is happening: a new object person is added at the same level of vehicles. Also, when I fill a person's information and then delete this person the models is not updated.

Answer 1

The schema you provide does not add a property 'gender' (as shown in your picture link). So I took 'title' instead of 'gender':
[
{
"key": "vehicles",
"items": [
"vehicles[].plate-number",
"vehicles[].color", {
"key": "people",
"type": "array",
"title": "People",
"items": [
"vehicles[].people[].name",
"vehicles[].people[].title"
]
}
]
}
]
I hope this is what you're looking for!
