title: OData filter is not working in my web api
body: <p>I didn't create OData controller, instead, I just installed OData package and add EnableQuery attribute to the IQueryable action method. Here is my method</p>
  
  <pre><code>    [HttpGet]
      [Route("WoundLocations")]
      [EnableQuery]
      public IQueryable&lt;WoundLocation&gt; GetWoundArea()
      {
          return _lookupService.GetWoundLocation().AsQueryable();
      }
  </code></pre>
  
  <p>And I call the action with the following url</p>
  
  <pre><code>  http://dev-xxx.xxxx.com/lookup/WoundLocations?filter=Side eq '0'
  </code></pre>
  
  <p>The returned result still has all the records in that table. Any thoughts?</p>
