Just do something as:

<components:LabelDateField id="df" 
                           width="100%" editable="true" 
                           text="{outerDocument.id_DateAdmin.text}"
                           selectableRange="{{rangeEnd : new Date()}}" 
                           change="{outerDocument.id_DateAdmin.text = df.selectedDate}"/>
