HLSJS with Secure Key and Api Load

Hi.

I have a working page with flowplayer + HLSJS + Secure Key.
Everything is working fine ;)

But now i want to add an external button to launch ( play ) the video.
If i know how to do it for a normal video :

$(function () {
// load clip object
$("button:first").click(function () {
flowplayer(0).load({
sources: [
{ type: "application/x-mpegurl",
src: "//source" }
]
});
});
});

I dont success to load the secure stream.
Firefox Dev Console show me that the keyfile is not loaded ( access forbiden )
But i dont know why.

On a same test page i have classic script and button load script.
first one works, second one not.

So how can i use Hlsjs secure with load button ?

Thanks

Start with the external button's flowplayer(0).load call and compare it with the working classic script on the same test page. Use the Firefox Dev Console to reproduce the forbidden keyfile request and determine why loading the secure stream differs; done means the secure stream loads and plays through the button without the access error.
