How can I get check value "{common.radio()}" in datatable?

I want get a radio check value in datatable.
I want to get the value when the button is pressed after all tasks are completed, not when a change event occurs.
for example, I want to get the value of the list with the radio button checked when I click the bottom choose button in the code snippet.

thank you.
