Extend doesn't seem to work in jquery plugin
<p>I'm creating a basic jquery plugin but the extend doesn't seem to work..</p>

<p>I'm calling the plugin in below manner</p>

<pre><code> $('#ccontainer').slide("/json/service.json",6000,700,'true','true','right','800px');
</code></pre>

<h2>Plugin</h2>

<pre><code>(function($) {

$.fn.slide = function(settings) {

    var options = {
        service : '',
        slideAnimationTime : 5000,
        slideSpeed : 800,
        onHoverPause : 'true',
        autoSlide : 'true',
        direction : 'right',
        width : ''
    };

    $.extend(options , settings);
    console.log(options.slideSpeed); //doesn't show up new settings as 700 in above case but instead shows old value 800 
}
</code></pre>
