Fullcalendar eventLimittext day value

Question

Hi I need to get eventlimittext day value.I shows and calls function when evenlimit exceed.

So I can get day value in eventLimitClick like

//in creating calendar

eventLimitClick :moreClicked,


function moreClicked(cellInfo, jsEvent) {  
    var event = cellInfo.date.format("YYYY-MM-DD HH:mm:ss");
    console.log(event)

I just gotta get the day value which exceed the limit

eventLimitText: function (numEvents) {
        //var event = cellInfo.date.format("YYYY-MM-DD HH:mm:ss");
        console.log("numEvents");
        console.log(numEvents);
 

In success i can get value but I can't get the day to pass controller with start data parameter. How can I get it

Thank you
