Full-Width-Responsive-jQuery-Slider not working properly?

Question

i had used Full-Width-Responsive-jQuery-Slider-Banner-Rotator-Plugin

http://www.jqueryscript.net/slider/Full-Width-Responsive-jQuery-Slider-Banner-Rotator-Plugin.html 

to get full screen width and i implemented this in my website but i got an issue in this.

There are five dots on images.the slider is following the order of dots and displaying the images.whenever i click on any one of the dots(ie; on 4th dot) on the slider it is not continuing from that dot(ie; not showing 5th image after 4th) instead it is following the order of dots from where it was before(ie; displaying the 2nd one).

Any help would be appreciated.

html code:

<div class="banner">
<div class="slider">
<ul>
<li> <a href="#"> <img src="slider01.jpg" width="1920" height="447"> </a> </li>
<li> <a href="#"> <img src="slider02.jpg" width="1920" height="447"> </a> </li>
<li> <a href="#"> <img src="slider03.jpg" width="1920" height="447"> </a> </li>
<li> <a href="#"> <img src="slider04.jpg" width="1920" height="447"> </a> </li>
</ul>
<div class="dots"> 
<a href="javascript:void(0);" rel="0" class="cur"></a> 
<a href="javascript:void(0);" rel="1"></a> 
<a href="javascript:void(0);" rel="2"></a> 
<a href="javascript:void(0);" rel="3"></a> 
</div>
<div class="arrow"> 
<a href="javascript:void(0);" class="btn-left">&lt;</a> 
<a href="javascript:void(0);" class="btn-right">&gt;</a> 
</div>
</div>
</div>

calling the plugin:

 <script type="text/javascript">

  $(document).omSlider({
    slider: $('.slider'),
    dots: $('.dots'),
    next:$('.btn-right'),
    pre:$('.btn-left'),
    timer: 12000,
    showtime: 1000

  });
  </script>

Jquery code:
