            <button type="submit" id="submit" class="btn btn-primary">Submit</button>
        </form>

    </div>

instead of `unbind()` use `off()` or directly do `$("form").submit();` — Serving Quarantine period, May 29 '17 at 11:41

To avoid these kind of problem you need to disable the button when it clicked — lalithkumar, May 29 '17 at 11:48
