Radio buttons do not work the same as a menu, you will not be able to bind them to a table in the wizard, this is not the intent for the radio button form type.
once the page has been created by the wizard, you should be able to give the radio buttons a dynamic value, but this cannot be accomplished in the wizard.
when the proprety panel is blank, it is because something was selected in design view that does not have properties.
make sure you are selecting the radio button itself in design view and not another element on the page like the label.
with the radio button selected, the property panel should show a dynamic button, his is where you can select dynamic properties for the button.
