AngularJs creating dynamic form to generate JSON schema

I need to create a form, so that i can create custom JSON schema and save the schema into db using a service.

JSON schema will be like : {"id":"schema_id","name":"schema_name","data":[{"id":"id","type":"text","attribute":"abc"}, {"id":"id","type":"text","attribute":"xyz"}]}

Also i need to have conditions in the form if type is list or some other value.
