Why doesn't the model change?

Question

Angular

There is a list with radio (displayed via ng-repeat), for the list element there is a model in which:

{
    radioValue: 0
}

I made a radio with the same name so that only 1 can be selected. When I select the desired one, the radioValue is set to "1", and the previously selected one becomes unselected, but the value "1" remains in its model, although "0" is needed.
Where is the mistake?

Answer 1

angular is dictative ) radio
