Add Item to List on JSLink with jQuery

Question

I have a JSLink on my Webpart Custom List, and I need to add an item before render a view.

(function () {
      var overrideCtx = {};

      overrideCtx.Templates = {};
      overrideCtx.Templates.Header = CustomHeader;
      overrideCtx.Templates.Footer = CustomFooter;
      overrideCtx.ListTemplateType = 100;
      overrideCtx.Templates.Item = CustomItem;
      overrideCtx.OnPreRender = CustomPreRender;

      SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCtx);

})();

function CustomPreRender(ctx){
   CotacaoAppDataUpdate(ctx);
   return true;
}

On CustomPreRender I call this function:

function CotacaoAppInsert(ctx, data){
   var listname = ctx.ListTitle;
   if (typeof(data) == 'undefined' || data.length == 0) return false;

   var itemType = GetItemTypeForListName(ctx.ListTitle);
   for(i in data){

      data[i]['Title']  = data[i]['Name'];
      data[i]['From']   = data[i]['Name'].split('/')[0];
      data[i]['To']     = data[i]['Name'].split('/')[1];

      var date = moment(data[i]['Date']+' '+data[i]['Time'], 'M/D/YYYY hh:mma');
      data[i]['Date'] = date.format('DD/MM/YYYY HH:mm');

      delete data[i]['Name'];
      delete data[i]['id'];
      delete data[i]['Time'];

      var item = $.extend({
         "__metadata": { "type": itemType }
      }, data[i]);

      $.ajax({
         url: _spPageContextInfo.siteAbsoluteUrl + "/_api/web/lists/getbytitle('" + listname + "')/items",
         type: "POST",
         contentType: "application/json;odata=verbose",
         data: JSON.stringify(item),
         headers: {
            "Accept": "application/json;odata=verbose",
            "X-RequestDigest": $("#__REQUESTDIGEST").val()
         },
         success: function (data) {
            console.log(data);
         },
         error: function (data) {
            console.log(data);
         }
      });
   }
}

ListTitle: Cotacao
Var itemType: SP.Data.CotacaoListItem

My var item on context:

Ask: "2.9834"
Bid: "2.9787"
Date: "23/04/2015 20:39"
From: "USD"
Rate: "2.9787"
Title: "USD/BRL"
To: "BRL"
__metadata: Object
__proto__: Object

Always I receive the error on console:

POST https://mydomain/sites/mysite/_api/web/lists/getbytitle('Cotacao')/items 400 (Bad Request)

I don't know what I'm doing wrong...

I have based this response and this post...

Edit

I've checked the responseText:

{
    "error": {
        "code": "-1, Microsoft.SharePoint.Client.InvalidClientQueryException",
        "message": {
            "lang": "pt-BR",
            "value": "Cannot convert a primitive value to the expected type 'Edm.DateTime'. See the inner exception for more details."
        }
    }
}

I don't know the correct date format from Sharepoint

Answer 1

I've solved error changing date format...

This:

  var date = moment(data[i]['Date']+' '+data[i]['Time'], 'M/D/YYYY hh:mma');
  data[i]['Date'] = date.format('DD/MM/YYYY HH:mm');

To this:

  var date = moment(data[i]['Date']+' '+data[i]['Time'], 'M/D/YYYY hh:mma');
  data[i]['Date'] = date.format('YYYY-MM-DDTHH:mmZ');
