jQuery live function with setTimeout

I'm trying to combine mouseenter, live and setTimeout function to make some animations

$(".kundenList li").live("mouseenter", function(){
    if ($(this).children().length > 0) {
        $(this).data('timeout', setTimeout( function () {
            $(this).children("div.description").css({opacity: '0'});

            $(this).children("div.blacklayer").animate({
                opacity: '0.85'
            }, 300);

            $(this).children("div.description").animate({
                top: "-=200px",
                opacity: '1'
            }, 300).css( 'cursor', 'pointer' );

            $(this).addClass("activeLI");
        }, 300));
    }
});

Html looks like this

<ul class="kundenList">
    <li>
        <img src="t3.png" class="kundenImg" />
        <div class="blacklayer" style="opacity: 0;"></div>
        <div class="description">
            <h3>Title</h3>
            <p>Description</p>
        </div>
    </li>
</ul>

Since I'm posting the question scrip apparently doesn't work :) . Anyone know why? Thanks.

PS I need live function since I'm loading new content over ajax

You cannot access li with this inside timeout function. Before timeout function define a variable, assing $(this) to it and use it in function like this (example):

$(".kundenList li").live("mouseenter", function(){
    var $this = $(this);
    if ($this.children().size() > 0) {

        $this.data('timeout', setTimeout( function () {
            $this.children("div.description").css({opacity: '0'});

            $this.children("div.blacklayer").animate({
                opacity: '0.85'
            }, 300);

            $this.children("div.description").animate({
                top: "-=200px",
                opacity: '1'
            }, 300).css( 'cursor', 'pointer' );

            $this.addClass("activeLI");
        }, 300));
    }
});

this inside setTimeout is referring to the global window object. Store a reference to this in a temporary variable, as shown below. Fiddle: http://jsfiddle.net/de7Fg/

$(".kundenList li").live("mouseenter", function(){
    var $this = $(this); //Reference to `$(this)`

    if ($this.children().length > 0) {
        $this.data('timeout', setTimeout( function () {
            // $this points to $(this), as defined previously
            $this.children("div.description").css({opacity: '0'});

            $this.children("div.blacklayer").animate({
                opacity: '0.85'
            }, 300);

            $this.children("div.description").animate({
                top: "-=200px",
                opacity: '1'
            }, 300).css( 'cursor', 'pointer' );

            $this.addClass("activeLI");
        }, 300));
    }
});
