Pleas help me.

I am building a tabbed layout for an application we are building,due to the large number of related objects to keep things organized.

We have multiple custom buttons on our custom objects which execute apex class methods and perform javascript functions. Here is an example :

{!requireScript("/soap/ajax/13.0/connection.js")} 
 
try 
{ 
var leadId = "{!Lead__c.Id}"; 
sforce.apex.execute("ActivityClass", "AddDisposition", {recordId:leadId, objectType:"Lead"}); 
window.location.reload(); 
} 
catch(err) 
{ 
alert("Error logging disposition: " + err.toString()); 
}

 How would I duplicate this button in visual force?

I tried includng the class as an extention in the VF page:

<apex:page id="tabLayout" showHeader="true" standardstylesheets="false" standardController="Lead__c" extensions="ActivityClass">

 But when I call the method:

<apex:commandButton value="Log Disposition"  action="{!AddDisposition}"/>

 I received: Save error: /apex/tabLayoutLead @36,79 action="#{AddDisposition}": Unknown method 'Lead__cStandardController.AddDisposition()'

I have included both the ActivityClass and the tabbed VF page below:

ActivityClass:

/*
	Class summary: Functionality for logging dispositions on client and lead records
	Last modified by: J. Duhaney
	Last modified on: 11/8/2011
*/
global class ActivityClass {
	
	public static Boolean AddDisposition(List<Client__c> clients)
	{
		List<Task> tasks = new List<Task>();
		
		for (Client__c client : clients)
		{
			if (client.Disposition__c != null)
			{
				Task task = new Task();
				task.OwnerId = client.LastModifiedById;
				task.Subject = client.Disposition__c;
				task.WhatId = client.Id;
				task.Description = client.Notes__c;
				
				task.Priority = 'Normal';
				task.Status = 'Completed';
				task.ActivityDate = date.today();
				tasks.add(task);
				
				client.Disposition__c = '';
				client.Notes__c = '';
			}
		}
		
		insert tasks;
		update clients;
		return true;
	} 
	
	public static Boolean AddDisposition(List<Lead__c> leads)
	{
		List<Task> tasks = new List<Task>();
		
		for (Lead__c lead : leads)
		{
			Task task = new Task();
			task.OwnerId = lead.LastModifiedById;
			task.Subject = lead.Disposition__c;
			task.WhatId = lead.Id;
			task.Description = lead.Notes__c;
			
			task.Priority = 'Normal';
			task.Status = 'Completed';
			task.ActivityDate = date.today();
			tasks.add(task);
			
			lead.Disposition__c = '';
			lead.Notes__c = '';
		}
		
		insert tasks;
		update leads;
		return true;
	} 

	webservice static Boolean AddDisposition(Id recordId, String objectType)
	{
		if (objectType == 'Client')
		{
			List<Client__c> clients = [SELECT LastModifiedById, Disposition__c, Notes__c FROM Client__c 
									WHERE Id = :recordId];
		
			return AddDisposition(clients);
		}
		else if (objectType == 'Lead')
		{
			List<Lead__c> leads = [SELECT LastModifiedById, Disposition__c, Notes__c FROM Lead__c 
									WHERE Id = :recordId];
		
			return AddDisposition(leads);
		}
		else
		{
			return false;
		}
	}
	
	// Tests the add disposition functionality
	public static testMethod void TestAddDisposition()
    {    	
    	Client__c testClient = Unit_Tests.CreateTestClient();
    	testClient.Notes__c = 'Test notes';
    	testClient.Disposition__c = 'Email Sent';
    	upsert testClient;
    	
    	AddDisposition(testClient.Id, 'Client');
    	
    	Lead__c testLead = Unit_Tests.CreateTestLead();
    	testLead.Notes__c = 'Test notes';
    	testLead.Disposition__c = 'Email Sent';
    	upsert testLead;
    	
    	AddDisposition(testLead.Id, 'Lead');
    }
}
