The phonegap plugin onload = false does not affect

Question

I need to prevent the plugin from initializing automatically. Therefore, I have the following configuration

    <feature name="ADBMobile_PhoneGap">
      <param name="onload" value="false" />
      <param name="ios-package" onload="false" value="ADBMobile_PhoneGap" />
    </feature>

However, when I launch the application, the plugin is still initialized before all javascript calls to this plugin are completed. Any ideas what I'm doing wrong?
