              </div>

Answer 1

Just use a ng-click to change the ng-model text input to null:

<input type="radio" ng-model="form.Program " value="other" required ng-click="form.OtherProgram = null" />

EDIT:

If I understood here is an updated answer, use a custom variable disableOption set to false initially, then play with that with ng-click and you are done:

<label ng-init="disableOption = false">
   <input type="radio" ng-model="form.Program" value="custom" ng-click="disableOption = true"  required /> Customize
</label>
<label>
   <input type="radio" ng-model="form.Program " value="other" ng-click="disableOption = false" required /> Provide Script
</label>
<input type="text" ng-model="form.OtherProgram" ng-disabled="disableOption === true" name="Program_Other" ng-required="form.Program != 'other'" />
