I have this bash function doing the job for qweb views. it should work for that one too or you can modify.

#!/usr/bin/env bash
fnc_reset_view() {
    if [[ -z "${1}" || -z ${2} || -z ${3} ]]; then
        echo "required: host user password view-id"
        exit 1
    fi

    host=${1}; shift;
    login=${1}; shift;
    password=${1}; shift;
    templates=${@}

    headers="-H 'Content-Type: application/x-www-form-urlencoded' -H 'Cookie: local-dev=1; website_lang=en_US; session_id=add15ae1c084759fdabaf986b4562c206403bed4'"

    echo "------> login"
    eval "curl --data \"login=${login}&password=${password}\" ${host}/web/login ${headers} > /dev/null"

    for t in ${templates}; do
        echo ""
        echo "------> ${t}"
        eval "curl -d \"templates=${t}\" -X POST ${host}/website/reset_templates ${headers} > /dev/null"
    done;
}
shift;; fnc_reset_view ${@}

resetview.sh "127.0.0.1:8090" "user" "password" "template_id"

it doesn't do anything else than reloading from disk. just in case, backup your database!
