title: Kendo UI Cascading ComboBox: Child not disabled on clearing parent combobox
body: <p>I am using Kendo UI MVC version "<strong>version:2016:1.112.545</strong>" in our project and there is a bug in Cascading ComboBox which can be reproduced in Telerik Demos in <strong>ASP.NET MVC</strong>, <strong>HTML5/JavaScript</strong>, <strong>JSP</strong> and <strong>PHP</strong> (<a href="http://demos.telerik.com/kendo-ui/combobox/cascadingcombobox" rel="nofollow">http://demos.telerik.com/kendo-ui/combobox/cascadingcombobox</a>).</p>
  
  <p>(Note: <strong>Text in the ComboBox needs to be typed</strong>)  </p>
  
  <p><strong>Steps to reproduce</strong>:<br>
  Visit the given URL.<br>
  Type letter b in Categories ComboBox and select Beverages<br>
  Type letter c in Products ComboBox and select Chai<br>
  Type letter p in Orders ComboBox and select Portland<br>
  Now clear the text in Categories ComboBox and it will populate all categories, But don't select any of them, just click outside<br>
  Notice that content in all the ComboBoxes are cleared, But Orders dropdown is still accessible and clicking on it will populate all the orders.  </p>
  
  <p>(Note: I checked it in Chrome and Firefox, Also just clicking on the dropdowns does not reproduce this issue. Please follow the instructions as it is)  </p>
  
  <p>If someone knows a fix or hack please share it.<br>
