Image upload after jquery validation using AJAX

I am using CodeIgniter. I am trying to upload the image using AJAX after jquery validation but it's not working. Jquery validation is working in case field is empty. After filling all the fields and clicked on submit button then my page refreshed. It's not calling the controller.

Would you help me out?

$("#primary").validate({
    errorElement: 'div',
    rules: {
        first_name: {
            required: true,
            alphabets: true,
            minlength: 3
        },
        last_name: {
            alphabets: true            
        },
        profile_pic: {
            extension: "png|jpeg|jpg|gif"                      
        },
    },

    messages: {
        profile_pic: {
            extension: "Only PNG , JPEG , JPG, GIF File Allowed",
        },  
    },

    submitHandler: function(form)
    {
      var formData = new FormData(this);

            $.ajax({
                url: baseUrl + "/AddMember/addMembers",
                type: 'POST',
                //data: $('#primary').serialize(),
                data:formData,
                dataType: 'json',
                success: function(data) 
         {                  
            if (data.error == "true")
            {           
             //success message
            } 
          else {
               //error message
               }
          }

            });
    }

});

Controller code

    $config=['upload_path'   =>'./uploads/images',
             'allowed_types' =>'gif|jpg|png|jpeg',
             'file_name'     =>uniqid().time().date("dmy")
             ]; 
            if ($this->upload->do_upload('profile_pic'))
            {
            $profile_pic_set = $this->upload->data('file_name');
            }
            else{$profile_pic_set = "";//set empty value if user not uploading any image
 }
                $this->load->library('upload', $config);
                $data = array(
                  'first_name'  =>  trim($this->input->post('first_name')),
                  'last_name'   =>  trim($this->input->post('last_name')),
                  'profile_pic' =>  $profile_pic_set
                   );   
                    print_r($data); //here I am getting profile_pic empty.

html

    <?php echo form_open_multipart('','id="primary"'); ?>
              <input type="text" name="first_name" id="first_name" class="form-control"  placeholder="First Name">
              <input type="text" name="last_name" id="last_name" class="form-control"  placeholder="Last Name">
<input type="file" name="profile_pic" id="file_upload">
              <button type="submit" class="btn btn-primary btn_new">Submit</button>
              <?php echo form_close(); ?>

TypeError: Argument 1 of FormData.constructor does not implement interface HTMLFormElement

Your problem is inside FormData(this). The this represents the validator itself, not the form object. The form object is represented by the form argument that is passed into the submitHandler.

So FormData() should contain the form argument.

Also, need to set the Ajax processData and contentType parameters to false...

submitHandler: function(form){
    var formData = new FormData(form);
    $.ajax({
        url: baseUrl + "/AddMember/addMembers",
        type: 'POST',
        data: formData, 
        dataType: 'json',
        processData: false,
        contentType: false,
        ....
