Posting data from a single table row asp.net mvc

I'm still quite new to MVC and I'm wondering if I am implementing the following in a correct way.

I have a table that is being build in a foreach loop. On each row there is a dropdown box. I attached an eventlistener to the dropdown for on change using jQuery. In the onchange event I post my data. Now my biggest concern is how to retrieve the data for the row that was changed. I'm currently using a hiddenfield for this. In webforms, this would have been a simple repeater and than all the data would be available on postback. Please find a basic version of my loop below.

@foreach (var item in Model)
{
<tr>
    <td>
        @Html.DisplayFor(modelItem => item.Bar)
    </td>
    <td>
        @Html.DropDownListFor(modelItem => item.Foo, new SelectList(item.Foos, "Id", "Name", item.FooID), htmlAttributes: new { @class = "form-control ddlFoo" })
        @Html.HiddenFor(modelItem => item.Bar, htmlAttributes: new { @class = "hfBar" })
    </td>
</tr>
}

So is this the correct approach? Or what would be a better way? Thank you for helping out a MVC newbie
