Asp.Net MVC5 dropzone js send with paramters - asp.net-mvc

Question

I want to post to a controller using bs-stepper and dropzone js together. How can I capture data in Controller?
html page, script and entity class and controller are below. I wonder where am I doing wrong
my scripts
document.getElementById("dropzone-yukle").addEventListener("click", function (event) {
event.preventDefault();
const form = document.getElementById('stepper-form');
formData = new FormData(form);
var object = {};
formData.forEach(function (value, key) {
object\[key\] = value;
});
var jsonData = JSON.stringify(object);
let params = { model: jsonData };
myDropzone.options.params = params;
myDropzone.processQueue();
});
Controller
[HttpPost]
public ActionResult OdaForm(ent_ODALAR model, HttpPostedFileBase[] files)
{
}
Entity class
public class ent_ODALAR
{
public long id { get; set; }
public int oda_no { get; set; }
public string oda_adi { get; set; }
public string oda_aciklamasi { get; set; }
public string oda_turu { get; set; }
public double oda_fiyati { get; set; }
public int oda_max_sayisi { get; set; }
public string oda_durumu { get; set; }
public int sira { get; set; }
public bool durum { get; set; }
public string oda_resim { get; set; }
}
