Enable and disable ExtJS tooltip from toolbar items

In my toolbar there is checkbox used for enabling and disabling tooltip. If the checkbox is checked then I should enable tooltip an开发者_JS百科d it is working if not then I should disable it also working. After disabling tooltip, when click on toolbar not on any item in the toolbar then also it is enabling.

toogleTooltip is a handler of checkbox

function toggleTooltip() {
    debugger;
    if (Ext.getCmp("msai_tool_tip").checked) {
        Ext.QuickTips.enable();
        while (!Ext.QuickTips.isEnabled())
            Ext.QuickTips.enable();
    } else {
        Ext.QuickTips.disable();
        while (Ext.QuickTips.isEnabled())
            Ext.QuickTips.disable();
    }
}

This is my toolbar creation code:

Ext.QuickTips.init();
var tb = new Ext.Toolbar({
    id: 'form_menu_bar',
    renderTo: Ext.get('newproducttitle').dom,
    items: [{
        tooltip: {
            text: "Click on this button to generate the template and save it in server.",
            title: "Save",
            xtype: "quicktip"
        },
        iconCls: 'msai_save_template',
        handler: generateTemplate

    }, {
        tooltip: {
            text: "Click on this button to generate the template.",
            title: "Save to clipboard",
            xtype: "quicktip"
        },
        iconCls: 'msai_save_clipboard',
        handler: generateTemplateClipboard
    }]
});

Please suggest some solution so that I should not show tooltip, if user click on toolbar not in any item.
