title: KnockoutJs & Asp.Net MVC 4 - Changing View Model depend on selected type
body: <p>I'm working with MVC 4 and KnockoutJs and I get a stuck with this scenario</p>
  
  <p>I have an object (called parent) which have a property named ChildType</p>
  
  <p><strong>_ If ChildType = 1 ---> I will render Partial-A with ViewModel-A<br>
  _ If ChildType = 2 ---> I will render Partial-B with ViewModel-B</strong></p>
  
  <p>I found not much article or answer for my issue. Most of all, they suggest a master ViewModel, somehow it's the best way, but if we have more than 2 child-viewmodel, it means that the master viewmodel is so large. </p>
  
  <p>So, please help me to implement it.</p>
  
  <p>Regards..</p>
