Calculate a parameter of a user with JS

I am creating a web app fitness that allows me to calculate the BMI and body fat percentage (BF) of a person, but the method that implements in JS does not work and I have no idea why.

This is the view with the JS:

@model IEnumerable<FitnessWebApplication.Models.Measurement>

@{
    ViewBag.Title = "Index";
}

<h2>Your Measurements</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table class="table">


    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Weight)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Height)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Neck)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Waist)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Taken)
        </th>
        <th></th>
    </tr>

    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.Weight) kg
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Height) cm
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Neck) cm
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Waist) cm
            </td>
            <th>
                @Html.DisplayFor(modelItem => item.Taken)
            </th>
            <td>
                @Html.ActionLink("Edit", "Edit", new { id = item.ID }) |
                @Html.ActionLink("Details", "Details", new { id = item.ID }) |
                @Html.ActionLink("Delete", "Delete", new { id = item.ID })
            </td>
        </tr>
    }

</table>
