Ext.ux.grid.plugin.PagingSelectionPersistence - headercheckbox question

[billp]

Using this plugin: http://www.sencha.com/forum/newreply.php?p=706912 ( Ext.ux.grid.plugin.PagingSelectionPersistence ) works great, but

the only issue I am having is that the headerCheckbox is staying selected when changing pages.
Our store is called each time there is a sort or next page is selected.

Everything else but this works great. I'm sure it's something in what I have setup.
Any suggestions would be great.

This is the code from our grid:

Ext.define('Ext.property.widgets.TPDataGrid', {
    extend: 'Ext.grid.Panel',
    viewConfig: {
        loadMask : false
    },
    plugins : [ Ext.create('Ext.shared.utils.PagingSelectionPersistence') ],
    initComponent: function () {
        this.id = 'tPDataGrid';
        this.store = Ext.create('Ext.app.stores.TPListStore');
        this.height = 350;
        this.selModel = Ext.create('Ext.selection.CheckboxModel', {
            checkOnly: true,
            listeners: {
                selectionchange: function () {
                    var submitBtn = Ext.getCmp('submitButton'),
                        radioEmpty = Ext.isEmpty(Ext.Object.getKeys(Ext.getCmp('t_type').getValue()));
                        
                    if (Ext.getCmp('tPDataGrid').getPlugin('pagingSelectionPersistence').getPersistedSelection().length && !radioEmpty) {
                        submitBtn.setDisabled(false);
                    } else {
                        submitBtn.setDisabled(true);
                    }
                }
            }
        });
        this.columns = [
        ...... 

Thanks.
