monitorValid and formBind don't work

[dranix]

Hello everyone
I'm new to Ext Js, especially its grid, and it is wonderful library.
Today I have a problem, I have search and read many posts but I don't know why I don't work
I have a grid, and I use pop up add/edit
When the add form popup, I use monitorValid and formBind but the Save button is still enable
Would some one please help me?

        var BookItem = new Ext.FormPanel({
            border: false,
            frame: true,
            labelWidth: 70,
            monitorValid: 'true', // !Important
            items: [
            {
                xtype: 'textfield',
                name: 'id',
                id: 'id',
                hidden: true
            },
            {
                xtype: 'textfield',
                name: 'book_title',
                id: 'book_title',
                width: 100,
                fieldLabel: 'Book Title',
                allowBlank: false
            },
            {
                xtype: 'textfield',
                name: 'author',
                id: 'author',
                width: 100,
                fieldLabel: 'Author'
            }],
            buttonAlign: 'center',
            buttons:
            [{
                align: 'center',
                text: 'Save',
                handler: Add,
                formBind: 'true' // !Important
            }, {
                align: 'center',
                text: 'Cancel',
                handler: Cancel
            }]
        });

        var winForm = new Ext.Window({
            title: formTitle,
            modal: true,
            width: 275,
            autoScroll: true,
            bodyStyle: 'position:relative;',
            monitorResize: true,
            constrain: true,
            layout: 'fit',
            height: ht,
            closeAction: 'hide',
            layout: 'fit',
            items: BookItem
        });

        var CreateBookItem = function () {
            winForm.update = true;
            winForm.setTitle('Create' + " " + formTitle);
            BookItem.getForm().reset();
            winForm.show();
            if (winForm.getHeight() < ht) {
                winForm.setHeight(winForm.getHeight() + 32);
            }
            winForm.center();
        };

Any help is highly appreciated
Thank in advance

monitorValid and formBind take boolean values.
Assign true instead of 'true' to them.

I don't know what to say (stupid me)
Thank you very much
