is there anyway to use Ajax.Beginform with fluentbootstrap !?

I'm using Fluent bootstrap and I want to use something like Ajax Begin form but it doesn't recognize fluent helpers ....

how can I turn this form :

  using (var form = Html.Bootstrap().Form().Begin())
                         {
                            @Html.AntiForgeryToken()
                            @Html.ValidationSummary(true)
                            @form.InputFor(p => p.UniversityTypeCode, FormInputType.Number)
                            @form.InputFor(p => p.UniversityTypeTitle, FormInputType.Text)
                            @form.Submit(CoreMessages.Submit)
                         }

to be like this :

 @using (Ajax.BeginForm("CreateAjax", "UniversityType", new AjaxOptions() { OnComplete = "FormOnComplete", HttpMethod = "Post" }))
                     { // helper here }
