title: How to pass $filter parameters from SAPUI5 application
body: <p>I'm trying to make request link from input field to backend. My entity set is called ActionsSet, property of entity set is Applctn. I want to pass parameter from input field with Filter operator EQ. I can't figure out the proper way. Here is my code snippet.</p>
  
  <pre><code>onPress: function() {
   var oParameter = this.getView().byId("inp").getValue();
   if (oParameter == '') {
      var msg = 'Fill it!';
      MessageToast.show(msg);}
   else{
       var oModel = new sap.ui.model.odata.v2.ODataModel("&lt;SERVERURL&gt;/sap/opu/odata/sap/ZACTIONS_SRV/ActionsSet?$filter = Applctn eq '" + oParameter + "'");    
       }
  </code></pre>
  
  <p>Allright so I made it more simple. But I have this error 400 Bad request as </p>
  
  <p>/ZACTIONS_SRV/ActionsSet/$metadata?$filter%20=%20Applctn%20eq%20%27kjh%27</p>
  
  <p>Maybe problem is that request is in this format

  <p>And I guess I need that is this format to pass filter so backend, because this filter works in another app <a href="http://i.stack.imgur.com/RsGLW.png" rel="nofollow">Screen</a></p>
