SpServices.SpAutocomplete - problem with jquery

Hello,

Following this https://github.com/sympmarc/SPServices/wiki/SPAutocomplete I'm i'm trying to build an autocomplete field on SharePoint online(O365)

I have followed all instructions but cannot seem to make it work.

The following script works, it returns the current site name.

---------------------------------------------------------------------------------------------------------------------

<script language="javascript" src="/JS/jquery-3.1.0.min.js" type="text/javascript"></script>
<script language="javascript" src="/JS/jquery.SPServices-2014.01.min.js" type="text/javascript"></script>

<script language="javascript" type="text/javascript">

$(document).ready(function() {

alert("jQuery");
alert($().SPServices.SPGetCurrentSite());

});

</script>

---------------------------------------------------------------------------------------------------------------------

The actual script does not work:

---------------------------------------------------------------------------------------------------------------------

<script language="javascript" src="/JS/jquery-3.1.0.min.js" type="text/javascript"></script>
<script language="javascript" src="/JS/jquery.SPServices-2014.01.min.js" type="text/javascript"></script>

<script language="javascript" type="text/javascript">

$(document).ready(function() {
$().SPServices.SPAutocomplete({
sourceList: "List1", 
sourceColumn: "Title", 
columnName: "CurrentTitle", 
numChars: "3",
filterType: "Contains", 
ignoreCase: "true", 
highlightClass: "ms-bold", 
slideDownSpeed: "fast", 
debug: "true" 
});
});

</script>

---------------------------------------------------------------------------------------------------------------------

Does anyone have an ideea why it's not working? On-premise SP 2010 the exact same code works. Are there any limitations in SharePoint Online?

Thank you,

Catalin.
