I nailed down a weird behavior on JQM.
Since the page is based on JQM Boiler plate, I do not include the full page here. I published the code on jsfiddle.
Here is a summary of the behavior click actions:

Here is the extract of the relevant code:
<div id="oneapart"
data-add-back-btn="true"
data-back-btn-text="List"
data-role="page"
data-title="Home page">
I do not understand why the last click on the List button (a jquery mobile back button) requires 2 click to actually act on the link. In fact, the weird behavior is that a first click highlight the button in blue, but it remains as is without switching to the previous page until a second click happens.
Any help will be appreciated.
Regards.
This issue can be fixed by adding the
data-rel="back"to the button in the popup.The issue posted on Github has been marked as resolved because of that.
