在MVC5中绑定数字的空白字段时，显示占位符而不是0

Question

I am working on edit in MVC 5 with API Controllers . When user presses edit, a model with values fetched from db will be passed. However when adding a new data, empty model will be passed with following code

var Model = {
    Id: '',
    Type: ''
}
$.ajax({
    url: '@Url.Action("Action", "Control")',
    type: 'POST',
    data: { model: Model },
    success: function (data) {
    }

My web controller

public ActionResult Add(Model model)
{
    return View(model);
}

Now when I try to add the values, all the fields with string type will show placeholder but integers will show 0 instead of placeholder. I know its because I have passed empty field for numbers in my model but I need a workaround such that when empty numbers are passed it shows placeholder instead of displaying 0 using javascript or jquery

When you want to model binding to avoid 0 as default to integer type , please user null able integer value

 public int? Count { get; set; }

This will assign as null to integer property rather than zero when you post model from java script or jquery as black or empty.
