Sorting Table layouts for lists

I seem to have a problem getting the sort function working using the table Title Headings of the lists displayed in the front end.

For the Sermons List, when I hover over "Title" I get "<strong>Title</strong><br />Click to sort by this column" displayed but no sorting takes place. The same occurs for the other column headers. See www.stalfreds.org.au/sta-media/all-sermons

For the Series List I don't get any extra HTML when I hover over the column headings but again sorting does not happen. See www.stalfreds.org.au/sta-media/sermons-by-series
(I've also tried to sort the Series records in the BackEnd by dragging and dropping the record using the three vertical dots but the order does not hold after I refresh the Series Manager page. However sorting Speakers using this method worked.)

For the Speakers List there is HTML when I hover over the column headings but no sort occurs. See www.stalfreds.org.au/sta-media/sermon-speakers

I do have the Load IcoMoon CSS option set to "Yes" in the Layouts SermonSpeaker options. I'm also using Amazon S3 to store my mp3s.

Thanks.

Can you tell me which version of Joomla and SermonSpeaker you are using? And also if you use the default table layout or an adjusted one?

Looks like something isn't loaded related to JavaScript.

I think I see the problem.
Try adding at the top of your layoutfile. Just below the line with

I'm using:
Joomla! 3.2.3
SermonSpeaker 5.1.2

I edited
public_html/components/com_sermonspeaker/views/sermons/tmpl/table.php
with you suggestion but couldn't see any change. I think I need to spend some more time understanding table layouts ...

Thanks for your help Thomas.

I should have also said that I modified the following to remove the "Unpublished" label:
/public_html/components/com_sermonspeaker/views/sermons/tmpl/default_filters.php
And removed line 5:
<span class="label label-warning"><?php echo JText::_('JUNPUBLISHED'); ?></span>

I don't believe it has an impact on my current issue but happy to be proven wrong.

That shouldn't have any impact

I actually found the source of the problem. It's related to a change in Joomla when the Tooltips got changed from MooTools to Bootstrap. Since then the function which generates those titles no longer load core.js, which is required by it.
I did a PR to fix that at github.com/joomla/joomla-cms/pull/3410 . However that will only work for Joomla 3.3 (which will be released later this month).

In your case, either or should work.
