Date format in file Formetter.js using Web IDE

Question

Hi Experts,
I know that at the forum includes discussions which relate to date format, but I couldn't find topics of the date format using Formatter.js file in Web IDE.
To the point. It's the fragment of my index.html file, where can find resourceroots:
                              <script id="sap-ui-bootstrap"
                                               src="resources/sap-ui-core.js"
                                               data-sap-ui-libs="sap.m"
                                               data-sap-ui-theme="sap_bluecrystal"
                                               data-sap-ui-xx-bindingSyntax="complex"
                                               data-sap-ui-resourceroots='{"RbsNew": "./"}'>
                               </script>
My Formatter.js file looks like:
jQuery.sap.require("sap.ui.core.format.DateFormat");
jQuery.sap.declare("RbsNew.Formatter");
sap.ui.RbsNew.Formatter = {     
date : function (value) {
         if (value) {
                var oDateFormat = sap.ui.core.format.DateFormat.getDateTimeInstance({pattern: "yyyy-MM-dd"});
                return oDateFormat.format(value);                                     
        else {
      return value;
and it's located directly in the project directory - RbsNew.
I try use this file to format the date in Detail.view.xml file - exactly in Table. The fragment of code looks like:
<Text
            text="{
                               path:'Bdate',
                               formatter:'sap.ui.RbsNew.Formatter.date'
                }"/>
Unfortunately, I can't see the expected results.
Please help, because I don't know what I'm doing wrong.
Regards
Marcin

            text="{ 
                               parts : [ 'Bdate'], 
                               formatter:'RbsNew.Formatter.date' 
                }"/>
