jquery ui tab select method not working - jquery-ui

Question

I have two tabs with a submit button on each tab. When the button is clicked, I need to reload the content of that specific tab to get updated data from the server.
if (validStatus()) {
$.ajax({
//...
success: reloadTab
});
}
function reloadTab() {
var currentTab = $("#tabs").tabs("option", "active");
alert(currentTab);
$('#tabs').tabs('select', currentTab);
alert(currentTab);
}
When the button is clicked, the tab doesn't refresh. I see the first alert but not the second.
HTML is as follows:
Head:
<link rel="stylesheet" href="#this.Url.Content("//code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css")" />
<script>
$(function () {
$("#tabs").tabs();
});
</script>
Body:
<div id="tabs">
<ul>
<li>The first tab</li>
<li>the second tab</li>
<li>Success</li>
</ul>
<div id="Success">
testing
</div>
<div id="Tab1">
<fieldset >
<legend>Overview</legend>
<input type="button" id="submit1" value="submit" />
<br />
</fieldset>
<fieldset style="width: 700px;">
<legend>Overview</legend>
<div>
<table >
//updated with ajax
</table>
</div>
</fieldset>
<script>
//reloadTab is in here
</script>
</div>
<div id="Tab2">
<fieldset style="float:left; width:300px;">
<input id="submit2" type="button" value="submit"/>
</fieldset>
<fieldset style="float:left;">
<legend>Overview</legend>
<table>
//updated with ajax
</table>
</fieldset>
<script>.....</script>
</div>

Answer 1

Turns out tabs.('select', ...) is deprecated, using tabs.('option', 'active', index) fixed my issue. Solution found in this comment: https://stackoverflow.com/a/16033969/1463649

Do you see anything in the console of your browser? What browser are you using?
Try this to help you with the debugging.
function reloadTab() {
console.log($('#tabs')); // if this is an empty object, the element doesn't exist when you call this function
console.log($('#tabs').tabs()); // if this doesn't return 'function', you haven't included a library properly, maybe jquery ui, or jquery, or you're using an old version or something
console.log(currentTab); // if this is undefined then something went wrong and no tab is active
var currentTab = $("#tabs").tabs("option", "active");
alert(currentTab);
$('#tabs').tabs('select', currentTab);
alert(currentTab);
}
