Looping settime

I'm currently trying to circle around JavaScript.

What I want is the text that will be printed on the screen and then counted to the given number, for example:

"Test"

[1 sec pause]

"1"

[1 sec pause]

"2"

[1 sec pause]

"3"

This is my JS:

$(document).ready(function() {

    var initMessage = "Test";
    var numberCount = 4;    

function count(){

    writeNumber = $("#target");

    setTimeout(function(){
        writeNumber.html(initMessage);
    },1000);

        for (var i=1; i < numberCount; i++) {

    setTimeout(function(){
        writeNumber.html(i.toString());
    },1000+1000*i)};

};

 count();

});

This is my markup:

<span id="target"></span>

When I create the page, all I get is a "Test" followed by a "4".

I am not a JavaScript genius, so the solution can be quite simple. Any hints of what's wrong are much appreciated.

. (i) count. i 4. setTimeout, "4".

:

function createTimer(number, writeNumber) {
    setTimeout(function() {
        writeNumber.html(number.toString());
    }, 1000 + 1000 * number)
}

function count(initMessage, numberCount) {
    var writeNumber = $("#target");

    setTimeout(function() {
        writeNumber.html(initMessage);
    }, 1000);

    for (var i = 1; i < numberCount; i++) {
        createTimer(i, writeNumber);
    }
}

$(document).ready(function() {

    var initMessage = "Test";
    var numberCount = 4;


    count(initMessage, numberCount);

});

createTimer , "" , createTimer.
