jquery file upload in mvc while clicking on button

Here i am using jQuery-File-Upload to upload files. it is working fine. but here file is uploading when we select file, i need to upload file after clicking on submit button. Please help me how to solve this issue. i am using the following code.

   $('#fileupload').fileupload({


        dataType: 'json',
        url: '/VendorReport/UploadFiles',
        autoUpload: true,
        type: boolen,
        Default:true,
        success: function (msg) {

            alert(msg);

        }
    });


<input id="fileupload" type="file" name="files[]">
<input type="submit" id="btnup" value="Upload" />

You can stop auto-upload behavior by setting autoUpload: false

$('#fileupload').fileupload({
    dataType: 'json',
    url: '/VendorReport/UploadFiles',
    autoUpload: false,
    type: boolen,
    Default:true,
    success: function (msg) {
        alert(msg);

    }
});

EDIT

To upload file on clicking of button:

HTML

<input id="fileupload" type="file" name="files[]">
<input type="submit" id="btnup" value="Upload" />

jQuery

$(document).ready(function(){
    $("#btnup").click(function(){
         $('#fileupload').fileupload({
            dataType: 'json',
            url: '/VendorReport/UploadFiles',
            autoUpload: false,
            type: boolen,
            Default:true,
            success: function (msg) {
                alert(msg);
            }
        });
    });
});

EDIT

Or refer its documentation to follow official way--> How to start uploads with a button click

$('#fileupload').fileupload({
    dataType: 'json',
    url: '/VendorReport/UploadFiles',
    autoUpload: false,
    type: boolen,
    Default:true,
    success: function (msg) {
        alert(msg);
    }
    add: function (e, data) {
        data.context = $('<button/>').text('Click to Upload')
            .appendTo(document.body)
            .click(function () {
                data.context = $('<p/>').text('Uploading...').replaceAll($(this));
                data.submit();
        });
