Getting the form to submit when clicking the submi

I'm trying to submit the form when the button is clicked, however it wasn't as simple as i thought, i always end up getting a fp.getForm is not a function, although the submit handler is taken directly from the ExtJs doc, any clue?

Players.panel.Subscription = function(config) {
    config = config || {};
    Ext.apply(config,{
        border: false
        ,baseCls: 'modx-formpanel'
        ,process: 'mgr/player/getSubscribers'
        ,standardSubmit: true
        ,url: Players.config.connectorUrl
        ,baseParams: { action: 'mgr/player/getSubscribers' }
        ,buttons: [{
                    text: 'Export er'
                    ,formBind: true
                    ,type: 'submit'
                    ,handler: function(){


                            var fp = this.ownerCt.ownerCt,
                                form = fp.getForm();
                            if (form.isValid()) {
                                // check if there are baseParams and if
                                // hiddent items have been added already
                                if (fp.baseParams && !fp.paramsAdded) {
                                    // add hidden items for all baseParams
                                    for (i in fp.baseParams) {
                                        fp.add({
                                            xtype: 'hidden',
                                            name: i,
                                            value: fp.baseParams[i]
                                        });
                                    }
                                    fp.doLayout();
                                    // set a custom flag to prevent re-adding
                                    fp.paramsAdded = true;
                                }
                                form.submit();
                            }

                }
                }]

    });
    Players.panel.Subscription.superclass.constructor.call(this,config);

};

I also tried replacing the base class from modx-formpanel to formpanel and basicform with no success.

Thanks

It's because you have not a form panel. Try this:
