How to add interactivity to files that will be exported as .epub

Question

We're creating a short ebook for internal use and are having difficulties with adding interactive features. Not sure if it's the limitation of .epub files, although they are advertised as being able to be made media-rich on the adobe site.
Hyperlinks aren't clickable.
Videos don't pause.
Interactive buttons (for use on a checklist) don't work.
Pan and zoom on photos doesn't work.
I realize that these items would probably work if we were creating a folio, but since that's a 10 step process, and you need to have the adobe content viewer installed on your device to read them, we figured .epub would be a better way.
I'm using a mac.
I'm creating the file in indesign 2014,
The document set-up is for Digital Publishing, iPad resolution.
I'm using the various interactive features that are available.
I export as .epub, open on my iPad and nothing works except a video that doesn't pause.

Answer 1

You do not create movieclips on the timeline using code, though you can create them and add them as children of something that has been manually placed in the timeline.
To create a MovieClip using code you use: 
    var mc:MovieClip = new MovieClip();
If you need to add an image, then however you intend to acquire the image, after it has been acquired, you add it to the MovieClip using:  
    mc.addChild(img); 
where img is the instance of whatever form of object the image takes (Bitmap, Loader)
If you need to add a TextField to the MovieClip then you use: 
    var tf:TextField = new TextField();
    mc.addChild(tf);
and you can set up properties for the textfield such as the font and color and position as well after it has been instantiated (the first line).
