title: How to refresh controls after a model has changed?
body: <p>I build a web application using <a href="https://openui5.hana.ondemand.com/docs/api/symbols/sap.m.SplitApp.html" rel="nofollow noreferrer">SplitApp</a>, and I have a problem with my sap.m.Select controls. </p>
  
  <p>On page1.view I have 2 select controls, as it is shown <a href="http://jsbin.com/coparevumuga/2/edit?html,output" rel="nofollow noreferrer">here</a> (my thanks to <a href="https://stackoverflow.com/users/327864/allen">Allen</a> for his help). These select controls are populated from a database using ajax call.</p>
  
  <p>The problem is that when I add a new project to one of the firms on page2.view, I can't make  project select control on page1.view to refresh. </p>
  
  <p>For example, if I go to page1.view, select firm3 in the first select control, then go to page2.view and add project4 to firm3 and then navigate back to page1.view, I still see firm 3 is selected and there are only 3 projects available in the second select control.
  But if I select any other firm and then select firm3 again, I will see the 4th project in selection menu.</p>
  
  <p>So, the question is how do I refresh my project select control so I could see the newly added project without re-selecting a firm?</p>
