Bug@ionic2: ion-select doesn't clear the `checked` attribute when clearing the model

Hi, i’m using the ion-select with ngModel, when at start it will have the value undefined, after checking one and setting some values i make some processing with it and then set back the variable to undefined, when i was using standard html5 selects this would remove the checked value from option, but with the ion-select the option doesn’t reset, even if the value is undefined.

Have you found a solution for this?
