BUG radio-group [disabled]=

when using radio-group [disabled]="shouldDisabled"

when page first created this attribute works fine
but when I change the value of shouldDisabled on .ts
the view doesn't update

now I bind disabled attribute to every ion-radio for a workaround:

sorry for bad english

No source file or test is named. Start by reproducing the radio-group [disabled] binding and trace how changing shouldDisabled updates the view. Done means the group reflects later changes to shouldDisabled without binding disabled separately on each ion-radio.
