Remove selected files using jQuery

Question

Tried show selected images and remove images on click the images using jQuery.

removing image on click working fine, actually problem is it doesn't remove from the form .

$(document).ready(function() {
  /*multiple image preview first input*/

  $("#files").on("change", handleFileSelect);

  selDiv = $("#selectedFiles");
  $("#myForm").on("submit", handleForm);

  $("body").on("click", ".selFile", removeFile);

  /*end image preview */
});


var selDiv = "";
// var selDivM="";
var storedFiles = [];

function handleFileSelect(e) {

  var files = e.target.files;
  var filesArr = Array.prototype.slice.call(files);
  var device = $(e.target).data("device");
  filesArr.forEach(function(f) {

    if (!f.type.match("image.*")) {
      return;
    }
    storedFiles.push(f);

    var reader = new FileReader();
    reader.onload = function(e) {
      var html = "<div><img src=\"" + e.target.result + "\" data-file='" + f.name + "' class='selFile' title='Click to remove'>" + f.name + "<br clear=\"left\"/></div>";
      $("#selectedFiles").append(html);
    }
    reader.readAsDataURL(f);
  });

}

function handleForm(e) {
  e.preventDefault();
  var data = new FormData();

  for (var i = 0, len = storedFiles.length; i < len; i++) {
    data.append('files', storedFiles[i]);
  }

  var xhr = new XMLHttpRequest();
  xhr.open('POST', 'handler.cfm', true);

  xhr.onload = function(e) {
    if (this.status == 200) {
      console.log(e.currentTarget.responseText);
      alert(e.currentTarget.responseText + ' items uploaded.');
    }
  }

  xhr.send(data);
}

function removeFile(e) {
  var file = $(this).data("file");
  for (var i = 0; i < storedFiles.length; i++) {
    if (storedFiles[i].name === file) {
      storedFiles.splice(i, 1);
      break;
    }
  }
  $(this).parent().remove();
}

#selectedFiles img

  max-height: 200px;
  float: left;
  margin-bottom: 10px;
