title: Meteor changing another template reactively
body: <p>I loaded several templates at startup, 
  Once the page is loaded the user can select several items that will define the content of another template. That's where I am stuck.</p>
  
  <p>How after the call of my method and store the result in my session I can send it to the other Template.</p>
  
  <p>I have looked at Deps.Dependency I sure it is very simple in fact.</p>
