Name property does not work using Razor HiddenFor

I am creating several fields dynamically using Asp.net Razor and for this I am passing the index to a partial view and setting the name property of each field. Everything is working fine with all fields except Id and PersonId which are built using @Html.HiddenFor and are hidden.

If I set the name property as in the example below and pass the index, it works:

<label asp-for="Contato" name="PessoasContatosViewModel[@indice].Contato" class="control-label txt-contato">Contato</label>

If I try to use Razor @ Html.HiddenFor, the name property is not getting the index correctly (I'm not sure if it's because I'm using @name) and the fields are set to 0:

@Html.HiddenFor(model => model.Id, new { @class = "hid-id", @name = "PessoasContatosViewModel["+@indice+"].Id"})
@Html.HiddenFor(model => model.PessoaId, new { @class = "hid-pessoaId", @name = "PessoasContatosViewModel["+@indice+"].PessoaId"})

What's going wrong? Is there any way to set the name of these two fields so that the index is passed correctly.
