Apex method:

public PageReference getMyMethod(){
    ....
    return null;
}

Visualforce page action function:

<apex:actionFunction action="{!MyMethod}" name="myFunction" />

actionFunction works like a javascript function, so you can call it from anywhere at your page like this:

<apex:inputField value="{!something}" onchange="myFunction()" />

There are two methods to do this :

1)Use @Remote Action Call to call the method

2)Use ACtion Function and call on the event

Here are the documentations for the same
