How to add a js to specific mask

[dcarreroc]

hello,
I need to add a jquery plugin for a specific mask in my app, how can i do that?
I try this first:

class MyApp extends P4A {
public function __construct(){
parent::__construct();
$this->addJavascript(P4A_APPLICATION_PATH. "assets/jquery.plugin.js");
}
......
}

Not working
So I try in my mask:

class MyMask extends P4A_Base_Mask{
public function __construct() {
parent::__construct();
$p4a = p4a::singleton();
$p4a->addJavascript(P4A_APPLICATION_PATH. "assets/jquery.plugin.js");
}
}


Thanks 👍
