Set font-style on data-element

[drentsch]

Hi,
i have migrated from the previous version ( bootstrap-year-calendar ) to this version.
It works fine except one thing:
bevor i was able to create the data-element like this:
data[i] =
{
id: obj[0],
name: obj[1],
location: obj[2],
startDate: new Date(year, month, day),
endDate: new Date(year, month, day),
color: col,
font: fontclass
}

depends on the date fontclass defers to different class in the css, e.g bold or underline.
In the new version this is not working, just ignored.
Is there anayway to do that?

;any thanks
Dani
