title: Query Kendo UI DataSource
body: <p>I want to use the DataSource as a local DB where by I can query certain data. I tried the following:</p>
  
  <pre><code>this.get("productsSource").query({
      filter: { field: "dirty", operator: "eq", value: true} 
  });
  var dirty = this.get("productsSource").view();
  </code></pre>
  
  <p>This works great. However, the Drop Down List bound to this DataSource is now showing only the "dirty" records. As if the query affected the entire DataSource.</p>
  
  <p>What I am after is to just return certain records based on a filter criteria without changing the "view" of the DataSource.</p>
  
  <p>Is that doable?</p>
  
  <p>Thanks</p>
