Getting jQuery data

I'm developing an image upload, where you can upload multiple images. When people choose their images, along with Preview in jQuery , I show 2 fields, one of the link and another of the caption of the image. However, when the person clicks save, I can not get these two fields, the rest goes perfectly. What can it be?

The code of the main page:

        <div class="span6 upl">
            <div id="tamb">Tamanho esperado: 586px x 184px</div>
           <input id="files" name="files[]" type="file" multiple />
            <output id="result" />

        </div>

The js code:

<script>
 window.onload = function(){

    //Check File API support
    if(window.File && window.FileList && window.FileReader)
    {
        var filesInput = document.getElementById("files");

        filesInput.addEventListener("change", function(event){

            var files = event.target.files; //FileList object
            var output = document.getElementById("result");

            for(var i = 0; i< files.length; i++)
            {
                var file = files[i];

                //Only pics
                if(!file.type.match('image'))
                  continue;

                var picReader = new FileReader();

                picReader.addEventListener("load",function(event){

                    var picFile = event.target;

                    var div = document.createElement("div");

                    div.innerHTML = "<img class='thumbnail' src='" + picFile.result + "'" +
                            "title='" + picFile.name + "'/> <a href='#' class='remove_pict del'><i class=\"icon-remove\"></i></a> <div class=\"control-group\">                         <label class=\"control-label\" for=\"MEM_LEGEN_IMAGM\">Legenda</label>                          <div class=\"controls\"><input id=\"MEM_LEGEN_IMAGM\" name=\"MEM_LEGEN_IMAGM\" type=\"text\" class=\"input-xlarge\">     </div>                </div>         <div class=\"control-group pull-right linkImg\"><label class=\"control-label\" for=\"TXT_LINKX_URLXX\">Link</label><div class=\"controls\"><input id=\"TXT_LINKX_URLXX\" name=\"TXT_LINKX_URLXX\" type=\"text\" class=\"input-xlarge\">        </div>            </div>";

                    output.insertBefore(div,null);   
                    div.children[1].addEventListener("click", function(event){
                       div.parentNode.removeChild(div);
                    });         

                });

                 //Read the image
                picReader.readAsDataURL(file);
            }                               

        });
    }
    else
    {
        console.log("Your browser does not support File API");
    }
}
</script>

And finally, the PHP code:

            //INFO IMAGEM
