You need to change your method to:

public Boolean getIsItemSelected(){
    System.debug('---coming here---');
    return false;
}

Methods that can be accessed in Visualforce need to be defined as getters:

One of the primary tasks for a Visualforce controller class is to give developers a way of displaying database and other computed values in page markup. Methods that enable this type of functionality are called getter methods, and are typically named getIdentifier, where Identifier is the name for the records or primitive values returned by the method.

[SalesForce] calling an actionfunction reloads the page despite giving rerender attribute and says insufficient privileges in sites

Following existing advice here, making sure that an error is not to blame, see that the Apex controller class has been included in your site's approved components:

Public Access Settings | Apex Classes | Edit

Regardless of whether your actionFunction is calling a method that does nothing but return a value, that's when your controller is invoked. To prove this, simply remove the action portion of your actionFunction, like this:

<apex:actionFunction name="test" reRender="emptydiv">

Additionally, remember that you can't re-render a non-Visualforce component, such as a div. If you're trying to re-render a div, wrap the section in an outputPanel instead:

<apex:outputPanel id="emptyoutpan">
   ...
</apex:outputPanel>

Finally, a good practice to avoid hitting your head against the wall with sites is to create a custom tab and verify your work from there as well. Then when you hit errors you will see what errors are actually being thrown, rather than simply seeing an authentication page.

[SalesForce] apex:param not assigning value within apex:actionSupport for apex:inputCheckbox

The actionSupport tag is to enable AJAX support on the page and hence only works for AJAX requests. In order to get it working, all you need to do is put the "Selected:" portion in an outputPanel and add reRender to the actionSupport tag. See example code below that works:

<apex:page controller="ActionSupportParamDemoController">
<apex:form >
    <apex:repeat value="{!accounts}" var="account">
        <apex:inputCheckbox value="{!account.IsActive__c}">
            <apex:actionSupport event="onchange"
                                action="{!handleAccountCheckboxChange}"
                                reRender="ResultPanel">
                <apex:param id="account" name="accountId" value="{!account.Id}"
                            assignTo="{!targetAccountId}"/>
            </apex:actionSupport>
        </apex:inputCheckbox>
        {!account.Name}
    </apex:repeat>
</apex:form>
<apex:outputPanel id="ResultPanel">
    Selected: {!selectedAccountId}
</apex:outputPanel>

No change is required on the controller.
