title: kendo ComboBox find and select value if exists
body: <p>I have a kendo combobox, and also have a variable with a value.
  How can I search for the value in the combobox, and if exists, select it?
  All with javascript/Jquery</p>

  <pre><code>var movieId=10;
  
  
  var combo =$("#movies").kendoComboBox({
      dataTextField: "text",
      dataValueField: "value",
      dataSource: data,
      height: 100
  });
  </code></pre>
  
  <p>I can't find how to set the value having and Id. 
  So my question is how to set the selectedIndex or Value to the one I have, and if is not exists, set the selectedIndex to -1</p>
