    function bookingRoomForMeeting() {
        var ctx = new SP.ClientContext(appWebUrl);//Get the SharePoint Context object based upon the URL  
        var list = ctx.get_web().get_lists().getByTitle("MyCalendarList"); //Get the List based upon the Title
        var listCreationInformation = new SP.ListItemCreationInformation(); //Object for creating Item in the List

        listItem.set_item('Title', $("#txt_Title").val());
        var date = $("#txt_startTime").val();
        var dateTime = moment(date, 'DD/MM/YYYY HH:mm a').format("MM/DD/YYYY HH:mm a");
        listItem.set_item('EventDate', dateTime);
        var enddate = $("#txt_endTime").val();

        listItem.update();
        ctx.load(listItem);
        ctx.executeQueryAsync(
            Function.createDelegate(this, success),
            Function.createDelegate(this, fail)
           );
    }
function success() {
    alert("Completed");
}
function fail() {
    alert("operation failed");
}

Make sure to use internal names of the fields rather than the display name. Change Start Time to EventDate and End Time to EndDate. See Finding the internal name and display name for a list column for more information on internal field names.
