Access resource model stored in UIComponent from View Controller

Hi,

how I can access a resource model stored in the UIComponent created on SplitApp startup in Component.js file?

Code from Component.js:

sap.ui.core.UIComponent.extend("Test.Component", {

     init : function() {

          var i18nModel = new sap.ui.model.resource.ResourceModel({ "/i18n/messageBundle.properties"});

          this.setModel(i18nModel, "i18n");

     }

} );

How can I access that model in e.g. the Detail View Controller?

Thx.
