Describe the Bug
for example in radio group component, value property is string.
if I provide value="true" for ion-radio, I get 'true' as string from ngModel in ion-radio-group
this is the case for most of the components. segment, checkbox etc.

Steps to Reproduce
Steps to reproduce the behavior:

<ion-radio-group [ngModel]="val"> <ion-item> <ion-label>open</ion-label> <ion-radio value="true"></ion-radio> </ion-item> <ion-item> <ion-label>close</ion-label> <ion-radio value="false"></ion-radio> </ion-item> </ion-radio-group>

return value of val is now string.

Expected Behavior
value property should respect the provided data type.
