How to i add a custom style_formats with using data from the database on tinymce? (For ASP.NET MVC)

I use TinyMCE editor. And i want to create a custom inline styles for a span tag. But style datas should come from the database. In this way the data can be obtained.

    $(document).ready(function () {

        $.ajax({
            type: "POST",
            url: '@Url.Action("GetFormats", "Editor")',
            dataType: "json",
            success: function (formats) {
                $.each(formats, function (index, format) {
                    // Datas from database
                });
            }
        });
    });

and define tinymce

    tinymce.init({           
    selector: "textarea",
        theme: "modern",
        plugins: [
            "advlist autolink lists link image charmap print preview hr anchor pagebreak",
            "searchreplace wordcount visualblocks visualchars code fullscreen",
            "insertdatetime media nonbreaking save table contextmenu directionality",
            "emoticons template paste textcolor colorpicker textpattern imagetools"
        ],
        toolbar1: "insertfile undo redo | styleselect formatselect fontselect fontsizeselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image media",
        toolbar2: "cut copy paste | searchreplace | print preview removeformat | forecolor backcolor emoticons",

        image_advtab: true,

        style_formats: [
        {
            title: 'My_Style_Combo', inline: 'span', styles: { color: 'rgb(0, 0, 255)', fontFamily: 'comic sans ms,cursive', fontSize:'12px',textDecoration:'underline' } 
        }
       //------> How can I integrate my each data here like this format type?
        ]

    });

I'm sorry for my bad English if you have difficulty in understanding.

I hope it has been a true expression. Thank you in advance for your answers.
