Using setTimeout to delay timing of jQuery actions

Question

I am attempting to delay the swapping of text in a div. It should operate like a slider/carousel for text.

I must have the code wrong, as the final text replacement never happens.

Also, how would I animate introducing the replacement text (window blinds, for eg.)?

<html>
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
        <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
        <link rel="stylesheet" href="http://code.jquery.com/ui/1.9.1/themes/base/jquery-ui.css" />

        <script type="text/javascript">
$(document).ready(function() {

    $("#showDiv").click(function() {
        $('#theDiv').show(1000, function() {
            setTimeout(function() {
                $('#theDiv').html('Here is some replacement text', function() {
                    setTimeout(function() {
                        $('#theDiv').html('More replacement text goes here');
                    }, 2500);
                });
            }, 2500);
        });
    }); //click function ends

}); //END $(document).ready()

        </script>
    </head>
<body>

    Below me is a DIV called "theDiv".<br><br>
    <div id="theDiv" style="background-color:yellow;display:none;width:30%;margin:0 auto;">
        This text is inside the Div called "theDiv".
    </div><br>
    <br>
    <input type="button" id="showDiv" value="Show DIV">



</body>
</html>

The JavaScript setTimeout () function is used to delay the execution of certain actions or code placed directly in this function or another JS function. The delay or time is specified in milliseconds with the setTimeout function.
