Query Between date with Mongoose - node.js

Question

I used Mongo 3.2 on debian 8. Node 5.11.1 and Mongoose.
The object are stored
{
"_id": {
"$oid": "5756e710eb8863716246689a"
},
"id": 735842,
"employee_id": 477,
"matricule": "1020510",
"name": "",
"date_day": "2016-04-24T22:00:00.000Z",
"morning_status": "P",
"morning_time_start": "08:16",
"morning_time_end": "12:12",
"afternoon_status": "P",
"afternoon_time_start": "12:57",
"afternoon_time_end": "18:30",
"working_time_theorical": 28800,
"working_time_employee": 34140,
"extra_hours": 5340,
"extra_hours_week": 10680,
"extra_hours_month": 78120,
"comments": ""
}
I want to extract the data with the field : date_day
var reporticoSchema = mongoose.Schema({
id :
{
type:Number,
index:true,
required:true
},
employee_id :
{
type:Number,
index:true,
required:true
},
matricule :
{
type:String,
index:true,
required:true
},
date_day :
{
type: Date,
index:true
},
.....
var Reportico=module.exports = mongoose.model('Reportico',reporticoSchema)
var dateStart=new Date('2016-04-01').toISOString(),
dateEnd=new Date('2016-04-30').toISOString();
console.log('d',dateStart,dateEnd)
var employeeId={employee_id:521,date_day:{$gte:dateStart,$lte:dateEnd}};
//console.log('employeeId',employeeId)
Reportico.find(employeeId).exec(function(err, employees) {
console.log('result')
if (err)return console.log('err',err);
console.log('employees',employees)
})
I updated the code to add te format of the field date_day
The result is empty.

This is my consult with date, I using library http://momentjs.com/ to separate date
var searchParams = {};
var di = moment('2016-04-01', "YYYY-MM-DD").toArray();
var de = moment('2016-04-30', "YYYY-MM-DD").toArray();
searchParams['date_day'] = { $gte: new Date(di[0],di[1],di[2]), $lte: new Date(de[0],de[1],de[2]) };
searchParams['employee_id'] = 521
Reportico.find(searchParams).exec(function(err, employees) {
console.log('result')
if (err)return console.log('err',err);
console.log('employees',employees)
})
