How do add to a backbone form? Where in the schema does it go?

Question

Scout.models.Equipment = Backbone.RelationalModel.extend({
  schema:{
    asset_number:{ type:'Text' },
    notes: 'TextArea',
    tag:{ type: 'Text', validators: ['required']}
  },
  defaults: {
    id: null,
    name: null,
  }
