The property serial
is never declared on the vue instance and therefore is not reactive.
You could use Vue.set(this.data_object, "serial", response.data)
this registers it with vue so it will add observers to this variable and it will become reactive
or
declare the serial property on the data object
data(){
return{
data_object: {
serial: ""
},
}
},
