You can create a method binding and set to the component as an Action, ActionListener or valueChangeListener depending on the component.
e.g of create a methodbinding in your component class. The following example creates a method binding and sets as an action for the button component:
String methodName = "#{manualAdjustmentAction.createManualAdj}";
MethodBinding methodBinding = this.getFacesContext().getApplication().createMethodBinding(methodName, null);
this.createManAdjButton.setAction(methodBinding);
