Can't insert code into title

I am using the accordion plugin as well as the easy timer plugin to make things easier for readers to see when I update the posts. The code that I came up with is as follows:

[accordion clicktoclose="true" tag="p"]
[accordion-item title="Title 1"]
<p class="alignright">[countup date=2016/3/14/6:00][timer] ago[/countup]</p>

<ul>
	<li>Latest Chapter:</li>
	<li>First Chapter</li>
	<li>TGWP Index</li>
</ul>
[/accordion-item]
[accordion-item title="Title 2"]

[/accordion-item]
[/accordion]

What I am trying to do is to put the count-up timer code into the title, but after trying to save it, it says invalid title. Is there a way to get codes with brackets into other codes with brackets like this one?
