Can you try this,
<div id="tabs-1">
... ajax contents of user's list comes here....
plus a link <a href="users/add" onclick="return LoadData(this,'1')">add new user</a>
</div>
<div id="tabs-2">
... ajax contents of jobs's list comes here....
plus a link <a href="jobs/add" onclick="return LoadData(this, '2')">add new job</a>
</div>
<script>
$(function() {
$( "#tabs" ).tabs();
});
function LoadData(ths, d){
var baseUrlpath ='Your base url here';
var url = baseUrlpath + $(ths).attr('href');
console.log(url);
$( "#tabs-"+d ).load(url, function() {
console.log( "Load was performed." );
});
return false;
}
</script>
