  on: {
   click: this.clickHandler
  },
  // For components only. Allows you to listen to
  // native events, rather than events emitted from
  // the component using vm.$emit.
  nativeOn: {
   click: this.nativeClickHandler
  },
  // class is a special module, same API as `v-bind:class`
  class: {
   foo: true,
   bar: false
  },
  // style is also same as `v-bind:style`
  style: {
   color: 'red',
   fontSize: '14px'

  key: 'key',

  // assign the `ref` is used on elements/components with v-for
