Difference between using Binding and Value Attribute

Question

what is the deference between using binding and value attribute, when I use binding attribute at the time of Value change listener is behaving like action listener,
Ex:
If I use value attribute, at the time of value change listener the component is not showing the result in the component but when I use Binding attribute it is happening automatically. So I want to know how the binding attribute is working.
I know, at the time of binding attribute the component is creating an instance at the bean side, So even also how it is following the life cycle of the JSF Frame work, and also Please suggest me weather which one is better to use either Binding or Value?

The ValueChangeEvent is invoked after conversion and validation in the 3rd phase, while the model values are updated in the 4th phase. In the valueChangeListener method you normally use ValueChangeEvent#getNewValue() to get the new value after the change.

Use the 'binding' attribute to bind the component to the bean. If you don't need to precreate the component or do other things than getting/setting its value, then there is no need for the 'binding' attribute.
Read on those links if you want to know something more about the JSF lifecycle:
