Update files inside a Docker container and update it outside the container

I create an Ionic page inside the container using the container shell and I want to obtain the result files outside the container. I have the src/ folder in a docker volume, if I update the code it updates too in the container but not in the opposite direction. How can I obtain the updates that I make inside the container outside of it?

Dockerfile

FROM node:alpine3.16
WORKDIR /project-meals-mobile-frontend/

RUN npm install -g @ionic/[email protected]
RUN npm install

COPY src/ /project-meals-mobile-frontend/src/

EXPOSE 8100

docker-compose.yml

version: '3'

services:
  ionic:
    container_name: project-meals-ionic
    restart: always
    build: ./
    command:
      ionic serve -p=8100 --external
    volumes:
      - ./src:/app
      - ./node_modules/:/node_modules/
    ports:
      - "8100:8100"

I execute this to go into the container shell:

docker exec -it project-meals-ionic sh

Then I execute the command to generate a page:

ionic generate page schedule

It works if I do an ls I have the corresponding files:

drwxr-xr-x    1 root     root          4096 Jan  5 15:09 .
drwxr-xr-x    1 root     root          4096 Jan  4 21:24 ..
-rw-r--r--    1 root     root           637 Jan  5 15:09 app-routing.module.ts
-rw-r--r--    1 root     root          1170 Jan  4 14:28 app.component.html
-rw-r--r--    1 root     root          1939 Jan  4 14:28 app.component.scss
-rw-r--r--    1 root     root          1523 Jan  4 14:28 app.component.spec.ts
-rw-r--r--    1 root     root           703 Jan  4 14:28 app.component.ts
-rw-r--r--    1 root     root           578 Jan  4 14:28 app.module.ts
drwxr-xr-x    2 root     root          4096 Jan  4 19:28 folder
drwxr-xr-x    2 root     root          4096 Jan  5 15:09 schedule

I need this folder outside the container to edit the code and upload it to git.
