Calling a managed bean method when some button is clicked

java jsf primefaces backing-beans

I am new to JSF and want to have a button, which when clicked, will call a method of the backing bean. Is this possible or I have to use AJAX or something? I tried things like

<button onclick="#{myManagedBean.myMethod()}">MyButton</button>

But they didn't work. What's the normal way of doing it?

Edit:
That button is created by JqueryUI, and I am unable to change the button's type to commandButton. I am able to do only two customizations-
1. call javascript functions from that button
2. change the target of the form (inside which the button resides)
So, how can I call the backing bean method from these two ways, like from Javascript or on form submit?

In JSF you have action parameter for the JSF componenents which can be bound to a method in your managed bean. using this method binding you can invoke the method of your managed bean. 

<h:commandButton value="click" action="#{managedbean.method}"/>
