BootstrapValidator custom validation return message from language pack

if( value.match(/\d+/g) && value.match(/[a-zA-Z]+/g) ) {
                return {
                    valid: true,
                }
            }

            return {
                valid: false,
                //need to return message from language pack
            }
//language pack(en_US.js)
account: {
            'default': 'Account must contain at leas 1 number & 1 english letter'
        }
