django and dropzone how to post form

I have gone through django and dropzone. I have implemented drag and drop feature of dropzone in django. My templates look like:

<form id="add-multiple" class="dropzone" action="{% url "name_add" %}" method="post" enctype="multipart/form-data">
        {% csrf_token %}
    </form>
    <button id="submit-all" type="submit" value="Submit" form="add-multiple">
        Submit all files
    </button>

    <script src="{% static 'js/dropzone.js' %}"></script>
    <script type="text/javascript">
        Dropzone.options.myDropzone = {

            // Prevents Dropzone from uploading dropped files immediately
            autoProcessQueue : false,
            paramName: "files",

            init : function() {
                var submitButton = document.querySelector("#submit-all")
                myDropzone = this;

                submitButton.addEventListener("click", function() {
                    myDropzone.processQueue();
                    // Tell Dropzone to process all queued files.
                });

                // You might want to show the submit button only when
                // files are dropped here:
                this.on("addedfile", function() {
                    // Show submit button here and/or inform user to click it.
                });

            }
        };
    </script>

Here I am getting the css and uploading perfectly but when I submit it dont call the {% url "name_add" %} url I mean form is not posted and dont call that url.

I followed this tutorial http://ift.tt/1yW0oBf to achieve this.

First thing my form is not being post or say it is not calling the url in form action. Second there is not any use of my form that I have created in forms.py to upload a file. In the tutorial also there is no use of form. Why is that and without form how form can be submitted because view requires form.

Can anyone help me ?
