Input Number and MQTT

Hello Forum,
i started to connect my Arduino to Home Assistant using MQTT protocol.
I have to pass some parameters defined with input-number integration to Arduino then I create a button on the front end with the following code:

type: button
tap_action:
  action: call-service
  service: mqtt.publish
  service_data:
    topic: Hassio
    payload: '{{ states.input_number.box1.state | int }}'

The issue i am founding is that the payload is not the number of the input_number but it’s a string containing “{{ states.input_number.box1.state | int }}”.

What i did wrong?

Thanks in advance
Alessandro
