When a radio button list is on the form and the selection controls the visibility of other widgets on the form. If no item is selected the code is taking the value of the first item in the list as being selected (even tho it is not) and shows the widget.
When the form is completed it is also taking the value of the first option in the radio button list and populating the variable when not selected
Essentially behave like the AngularJS code. If the radio button list is not selected then don't populate the variable.
*Steps to reproduce the issue:*
place 3 radio buttons on a form and set the visibility condition of the three other widgets based on what is selected in the button list. The first one will always render visible even if not selected
*Component name and version:*
ng2-alfresco-form radiobutton. version 1.5.0
*Node version (for build issues):*
