MVC RenderPartial Shared Strongly Typed View

Question

I have a Strongly Types Partial View that I am trying to render from another Partial View

@{ Html.RenderPartial("Days", Model.DaysOpen, new ViewDataDictionary()); }

I have been folling advice based on the below ASP.NET MVC, strongly typed views, partial view parameters glitch

It allows me to create the parent(Centre) but does not create the Child (owned) Days entity.

Can anyone offer any advice

Details.cshtml

@model RCCMS.ObjectModel.Entities.Centre

@using (Html.BeginForm(null, null, FormMethod.Post, new { @class = "form-horizontal", Role = "form" }))
{
 @Html.ValidationSummary("Please correct the following errors:-")

    @{ Html.RenderPartial("Days", Model.DaysOpen, new ViewDataDictionary()); }

</fieldset>
}

And my Partial View (Days)

@model RCCMS.ObjectModel.Entities.Days

<div class="form-group">
@Html.Label("Days Open", new {@class = "col-md-5 control-label"})
<div class="col-md-10">
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Monday) Monday
            @Html.ValidationMessageFor(m => m.Monday, "*")
        </label>
    </div>
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Tuesday) Tuesday
            @Html.ValidationMessageFor(m => m.Tuesday, "*")
        </label>
    </div>
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Wednesday) Wednesday
            @Html.ValidationMessageFor(m => m.Wednesday, "*")
        </label>
    </div>
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Thursday) Thursday
            @Html.ValidationMessageFor(m => m.Thursday, "*")
        </label>
    </div>
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Friday) Friday
            @Html.ValidationMessageFor(m => m.Friday, "*")
        </label>
    </div>
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Saturday) Saturday
            @Html.ValidationMessageFor(m => m.Saturday, "*")
        </label>
    </div>
    <div class="checkbox-inline">
        <label>
            @Html.CheckBoxFor(m => m.Sunday) Sunday
            @Html.ValidationMessageFor(m => m.Sunday, "*")
        </label>
    </div>
</div>

The create action of the CentreController

public ActionResult Create()
{
        if (!Security.HasPemission(Permission.CanCreateCentres)) return View("AccessDenied");

        var model = new Centre();
        return (IsAjax()) ? (ActionResult)PartialView("Details", model) : View(model);
    }
