Setting the Default Binding Mode

The default binding mode applies when a model instance is created. You can overwrite the default binding mode after model creation.

Procedure

To change the default binding mode, call the setDefaultBindingMode method on the model as follows:
```
#!js
var oModel = new sap.ui.model.json.JSONModel();
oModel.setDefaultBindingMode(sap.ui.model.BindingMode.OneWay);
```
In this example, all new bindings for the model will have the one-way binding mode by default.
You can, however, only set supported binding modes as default binding mode. You can check if a binding mode is supported as follows:
```
#!js
var oModel = new sap.ui.model.json.JSONModel();
if (oModel.isBindingModeSupported(sap.ui.model.BindingMode.OneTime)) { // true
    oModel.setDefaultBindingMode(sap.ui.model.BindingMode.OneTime); 
}
```
Note
When you change the binding mode of an existing model instance, the existing bindings are not updated with the newly set binding mode.
