How to dynamically add attribute values to pug templates in veu? why didn't I render this?

this is my pug template

<template lang="pug">
  div
    form(
      id="form"
      method="POST"
      action=""
    )
      div(class="form-data")
        input(type="text" name="data" id="data" :value="data")
</template>

this is my vue data

 data () {
          return {
            data: "1111"
          }
        }

using js in mounted .
