Javascript Send Commands via AJAX on Click

Question

I'm looking to send multiple commands to an API with the click of a button using a function, but the code doesn't seem to be working. Any idea what I'm missing?

<html lang="en">

<body>

<div class="container">
<p><a class="btn btn-primary" onclick="L3change('Top','Bottom','Single')">L3 Test</a></p>
</div>

<script>
    function L3change(topline, bottomline, singleline) {
    $.ajax({url: "192.168.200.189:8088/API/?Function=SetText&Input=L3&SelectedName=L3 Single In.Text&Value=" + topline});
    $.ajax({url: "192.168.200.189:8088/API/?Function=SetText&Input=L3&SelectedName=L3 Single Out.Text&Value=" + topline});
    $.ajax({url: "192.168.200.189:8088/API/?Function=SetText&Input=L3&SelectedName=L3 Top In.Text&Value=" + bottomline});
    $.ajax({url: "192.168.200.189:8088/API/?Function=SetText&Input=L3&SelectedName=L3 Top Out.Text&Value=" + bottomline});
    $.ajax({url: "192.168.200.189:8088/API/?Function=SetText&Input=L3&SelectedName=L3 Bottom In.Text&Value=" + singleline});
    $.ajax({url: "192.168.200.189:8088/API/?Function=SetText&Input=L3&SelectedName=L3 Bottom Out.Text&Value=" + singleline});
    }
</script>
