MVC Business Logic versus Display/UI Logic

So, I'm using the code below to show a couple of elements on the page on initial load.

<script type="text/javascript">

    $(function(){
        @if (ViewBag.PageFunction == "Edit" && Model.ProductType.ProductTypeName == "Book")
        {
            @:$('#product-isbn').show();
        }

        @if (ViewBag.PageFunction == "Edit" && Model.HasBulkDiscount == true)
        {
            @:$('#product-bulk-discount').show();
        }
    });

</script>

We've recently moved to MVC and my manager and a co-worker are telling me that the top control structure is business logic but the bottom one is not business logic, and that I should not have business logic in my view.

I disagree and feel like this is perfectly valid code to have in my view. Am I right or am I wrong?

My manager also told me I shouldn't be using @Html.LabelFor() in my view either because it is not reusable. Here's an example of how I'm using it.

<div class="form-group">
    <p>@Html.LabelFor(p => p.ProductName, new { @class = "col-sm-12" })</p>
    <div class="col-sm-12">
        @Html.TextBoxFor(p => p.ProductName, new { @class = "form-control" })
    </div>
</div>

Not sure if I understand that reasoning either.
