I'm struggling to get this to work. I'm not seeing the data getting saved from the checkbox's too and have tried many different iterations. 

I have read other posts but have tried their solutions and neither of them have worked. ( post 1, post 2 )

Here are a few attempts:

//------------- Latest attempt

@model EPiServer.XForms.Parsing.SelectFragment


@foreach (EPiServer.XForms.Parsing.SelectOption selectoption in Model.Options)
{
		var refName = selectoption.Id.Replace(" ", "").Replace(".", "").Replace(",", "");
		

			
			
			@selectoption.Value
		
	}
    @Html.ValidationMessage(@"" + Model.ValidationReference + "")


//------------- Original code


    @if (!string.IsNullOrEmpty(modelLabel))
    {
        @modelLabel
    }
    @foreach (EPiServer.XForms.Parsing.SelectOption selectoption in Model.Options)
    {
        

            @Html.CheckBox(Model.Reference, selectoption.SelectedItem, new { id = Model.Reference + "-" + selectoption.Value })
            @Html.Raw(selectoption.Text)
        
    }
    @Html.ValidationMessage(@"" + Model.ValidationReference + "")
