How can I make the popup with empty fileds and create new record?

Question

I would like to use a popup to create new record.
I created a af:popup by drag and drop a VO from data control to jsff. then, I created a button and place a af:showPopupBehavior. I was able to popup window by click the button.
however, the window filled with the information from the 1st record. and when I select a record in table and click popup, the popup is filled with that record.
How can I make the popup with empty fileds and create new record by saving the popup?
Thanks

You can have edit and new buttons, in the PopupFetchEvent identify button source (using popupFetchEvent.getLaunchSourceClientId()) if new button clicked clear the binding using below code.
If you want to see empty fields, in the popup PopupFetchEvent clear the input component bindings.
resetBindingValue("#{bindings.<componentid>.inputValue}", null);
    public static void resetBindingValue(String expression, Object newValue) {
        FacesContext ctx = FacesContext.getCurrentInstance();
        Application app = ctx.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = ctx.getELContext();
        ValueExpression valueExp = elFactory.createValueExpression(elContext,expression,Object.class);
        Class bindClass = valueExp.getType(elContext);
        valueExp.setValue(elContext,newValue);
    }
