Struggling with this ajax zendframework code

PHP
1

I have the ff error from firebug;

POST http://gepm.dev/members/getMembers 404 Not Found

the jquery code is like this

function getGroupMembers()
{
    if($("#GroupsId").val() != '')
    {
        var data = 'id='+ $("#GroupsId").val();
        var url= "/members/getMembers";

        $.post(url, data, function(resp)
        {
           console.log(resp);
        });
    }
}

and the zend controller action is like so

    public function getMembersAction()
    {

        echo $this->getRequest()->getParam('id');
    }

basically just for now get the data that was posted to the action.

Please help if you can.
