Still having issue with this...
in toolbar:
{
type: 'button',
label: "label",
attr: 'id="toolbar_button"'
}
in reftresh event:
refresh: function() {
$('#toolbar_button').tooltipster({
content: $('<strong>this is a text</strong>')
});
}
It works but in console I get output:
Tooltipster: one or more tooltips are already attached to the element below. Ignoring.
