How to disable buttons based on data model values? - asp.net-mvc

Question

I am building a mini online shopping CMS project for collage.
I finished the project and now I want to add a feature where I have limited quantity of products.
When the quantity is equal to 0 then product is shown as 'out of stock' and my 'Add to cart' button becomes disabled.
I have added a 'quantity' property to my product class and now I need to change something in the Index view of the product.
I tried few options and it does not seem to work.
Here is the code for the Index.cshtml page.
#model IEnumerable
<Product>
#{ ViewData["Title"] = "Products"; }
<h1 class="display-4 pb-5">All Products</h1>
<div class="row">
#foreach (var item in Model)
{
<div class="col-4">
<div class="ajaxbg d-none">
<img src="~/Images/ajax_loader.gif" />
<p class="lead alert alert-success text-center d-none">
The product has been added!
</p>
</div>
<img src="~/Media/Products/#item.Image" class="img-fluid" alt="" />
<h4>#item.Name</h4>
<div>
#Html.Raw(item.Description)
</div>
<p>
#item.Price.ToString("C2")
</p>
<p>
<a asp-controller="Cart" asp-action="Add" asp-route-id="#item.Id" data-id="#item.Id" id="addToCartButton" class="btn btn-primary addToCart">Add to cart</a>
</p>
#if (item.Quantity == 0) { }
</div>
}
#if (ViewBag.TotalPages > 1) {
<div class="d-flex w-100 justify-content-center">
<pagination page-count="#ViewBag.TotalPages" page-target="/products" page-number="#ViewBag.PageNumber" page-range="ViewBag.PageRange"></pagination>
</div>
}
</div>
#section Scripts {
<script>
function DisableBtn() {
document.getElementById("addToCartBUtton").disabled = true;
}
$(function() {
$("a.addToCart").click(function(e) {
e.preventDefault();
let ajaxDiv = $(this).parent().parent().find("div.ajaxbg");
ajaxDiv.removeClass("d-none");
let id = $(this).data("id");
$.get('/cart/add/' + id, {}, function(data) {
$("div.smallcart").html(data);
ajaxDiv.find("img").addClass("d-none");
ajaxDiv.find("p").removeClass("d-none");
setTimeout(() => {
ajaxDiv.animate({
opacity: 0
}, function() {
$(this).addClass("d-none").fadeTo(.1, 1);
$(this).find("img").removeClass("d-none");
$(this).find("p").addClass("d-none");
});
});
});
});
});
</script>
}

Try this
#If(Model!=null)
{
#foreach (var item in Model)
{
..........
<p>
#if (item.Quantity == 0) {
<a disabled class="btn btn-primary addToCart">Add to cart</a>
}
else
{
<a asp-controller="Cart" asp-action="Add" asp-route-id="#item.Id" data-id="#item.Id" id="addToCartButton" class="btn btn-primary addToCart">Add to cart</a>
}
</p>
}
}
