Angular JS on Refresh loosing CSS - asp.net-mvc

Question

So weird things are happening. I have an angular page with routing, repeat etc., and it works fine. But if I press F5 in it, it always looses the CSS. I'm refreshing a partial view which is tied to a _Layout. So whenever I browse thru my page and press F5 on any page which is a partial view ONLY the partial view is refreshed and I loose all my CSS and layout elements. Why is that?
I'm using MVC btw.
For routing I'm using:
$routeProvider
.when('/Account/PersonalInformation', {
templateUrl:
function (params) {
return "/Account/PersonalInformation/"
}
})
EDIT
as per request, PersonalInformation.cshtml, nothing special:
#using (Html.BeginForm("PersonalInformationJSON", "Account", FormMethod.Post, new { id = "editUserForm" }))
{
<div class="account_container">
<div class="user_data background_black">
<div class="panel panel-default width-470 no_border">
<div class="panel-body head_title_background no_padding"><h4 class="white margin-left30 bold">PERSONAL_DATA<h4></div>
</div>
<ul>
<li>
<div class="label">
#Html.Label(FIRSTNAME)
#Html.Label(":")
</div>
#Html.TextBoxFor(m => m.Edit.FirstName, new { #class = "textbox_disable", #readonly = "readonly" })
</li>
<li>
<div class="label">
#Html.Label("LASTNAME")
#Html.Label(":")
</div>
#Html.TextBoxFor(m => m.Edit.LastName, new { #class = "textbox_disable", #readonly = "readonly" })
</li>
<li>
<div class="label">
#Html.Label(.("USERNAME"))
#Html.Label(":")
</div>
#Html.TextBoxFor(m => m.Edit.UserName, new { #class = "textbox_disable", #readonly = "readonly" })
</li>
<li>
<div class="label">
#Html.Label("BIRTHDATE")
#Html.Label(":")
</div>
<label class="textbox_disable">#Model.Edit.BirthDate.ToString("dd.MM.yyyy")</label>
</li>
<li>
<div class="label">
#Html.Label("TYPE_OF_LICENSE")
#Html.Label(":")
#Html.ValidationMessageFor(m => m.Edit.WebTypeOfLicense, "", new { #class = "red" })
</div>
#Html.DropDownListFor(m => m.Edit.SelectLicenseId, Model.Edit.WebTypeOfLicense, "Choose type of license", new { #class = "textbox",id="type_of_license" })
</li>
<li>
<div class="label">
#Html.Label("LICENSE_NUMBER")
#Html.Label(":")
#Html.ValidationMessageFor(m => m.Edit.IdentificationNumber, "", new { #class = "red" })
</div>
#Html.TextBoxFor(m => m.Edit.IdentificationNumber, new { #class = "textbox", id="licence_number" })
</li>
</ul>
}
Controller:
public ActionResult PersonalInformation(ManageMessageId? message, IndexPageModel model)
{
model.Edit = new EditModel();
model.Edit.Country = new SelectList(CommonDbService.GetAllCountry(), "Id", "Name");
model.Edit.WebTypeOfLicense = new SelectList(CommonDbService.GetAllLicense(), "Id", "Name");
WebUser user = WebUser.FindByUsername(User.Identity.Name);
ViewBag.StatusMessage =
message == ManageMessageId.ChangeDataSuccess
? "Your data has been changed."
: "";
UserDebitInformation userDebitInformation = UserDebitInformation.FindDebitInfoByUserId(user.Id);
model.Edit.UserName = user.UserName;
model.Edit.FirstName = user.FirstName;
model.Edit.LastName = user.LastName;
model.Edit.BirthDate = user.BirthDate;
model.Edit.SelectLicenseId = user.TypeOfLicence.Id;
model.Edit.IdentificationNumber = user.IdentificationNumber;
return View(model);
}
