Custom Binding with a List of a Custom Class request string is invalid

Question

I am having some troubles with my MVC application

I have created custom binders and they are working for everything except my list of QueryTags

    public class QueryTag
{
    [Key]
    public int QueryTagId { get; set; }
    public string TagName { get; set; }
    public bool IsChecked { get; set; }
}

In my Binder

            string tagName;
            int index = 0;
            List<QueryTag> tagList = new List<QueryTag>();

            while (!string.IsNullOrEmpty(tagName = request.Form["QueryTags[" + (index++) + "].TagName"]))
            {
                tagList.Add(new QueryTag()
                {
                    QueryTagId = int.Parse(request["QueryTags[" + (index) + "].QueryTagId"]),
                    TagName = tagName,
                    IsChecked = request["QueryTags[" + (index) + "].IsChecked"] == "ture,false"
                });
            }

            if (tagList.Count == 0)
            {
                bindingContext.ModelState.AddModelError("QueryTags[0]", "Something went wrong with the query tags");
            }
            else
            {
                model.QueryTags = tagList;
            }

and I am using a view with a jquery popup modal like so:

        <input type="button" value="Add Tags" id="QueryTagOpener" />
        <div id="QueryTagPopup" title="Query Tags">
            <div style="width: 25%; float: left">
                @for (int i = 0; i < Model.QueryTags.Count(); ++i)
                {
                    <div class="editor-field">
                        @Html.DisplayFor(model => model.QueryTags[i].TagName)
                    </div>
                    <div>
                        @Html.EditorFor(model => model.QueryTags[i].IsChecked)
                    </div>
                }
            </div>
        </div>

The request.Form["QueryTags[" + (index++) + "].TagName"] is always null.

I am assuming it has something to do with the jquery popup but I have tried implementing the view like I am for other properties that work with no luck.

I am sure it is something simple but have been bouncing around the internet for hours banging my head and can't figure it out.

Any help would be appreciated.
