Call Openlayers3 control from a buttom

[kukuma]

Hello,
I want to call an Openalayers3 control from a buttom in a toolbar.
I've made serveral buttoms with a function and work. But now I'm trying to do the same with an openlayers3 control and I don't know how to do that.
In other versions of Ext JS and Openlayers, it could be done.
Here are some examples about what I'm doing:

var toolBar = new Ext.toolbar.Toolbar({
items: [
{
xtype: 'button', /*Button Zoom Alejar*/
baseCls: 'btn-button',
html: '<i class="fa fa-search-minus" aria-hidden="true"></i>',
tooltip: "Zoom Alejar",
listeners: {
click: function() {
var view = olMap.getView();
var zoom = view.getZoom();
view.setZoom(zoom - 0.5);
}
}
},
{
xtype: 'button', /*Button Full Screen*/
baseCls: 'btn-button',
tooltip: "Pantalla Completa",
listeners: {
click: function() {
olMap.addControl(new ol.control.FullScreen());
}
}
},
]
});

If I do that (olMap.addControl(new ol.control.FullScreen()) when I click in the button apears the openlayers button for Fullscreen in the map but it doesn't apear in the toolbar.
How can I do to put the control in the toolbar's button?
Thanks

This seems more like an openlayers question. With which version of Ext JS did this work for you?

There is an example here: https://github.com/vahid-sohrabloo/G...les/toolbar.js
I want to do something similar. But "new Ext.Action" instead of "new GeoExt.Action" but Ext.Action hasn't the control method.
