Docker Bind Mounts not working with mounted devices on Host

Hi, I am using bind mounts in a Docker container for a folder. Now I’m executing.
‘Kpart -av my.img’
and mounted /dev/mapper/loop01 to a directory which is subfolder in the folder bind mounted with the container . Now the data available on the image partition mounted on the host directory is visible. But it is not visible in the Docker container.

The folder is bind-mounted.

The data is available and visible inside the container when I restart the container. Please help me with the solution.
