Multimodel Support

You can set an additional model for an element or for the core by specifying a name for the model to identify it:

var oModel = new sap.ui.model.json.JSONModel();
// define data for that model
oModel.setData({
    		test: "Test", 
    		enabled: true
});

// define a name for that model
sap.ui.getCore().setModel(oModel, "myModel");

To create property bindings for this model call

oText.bindValue("myModel>/test").

You can also create aggregation bindings for this model by calling:

oListItem.bindProperty("text", "myModel>text");
oComboBox.bindItems("myModel>/items", oListItem);

You specify the model name and following the > sign you specify the binding path to the values in the model that is to be bound.
