Show cell bubble

Dear sir/madam, I'm currently using the trial version of your calendar and scheduler to see if it meets the requirements of the solution that we're developing. I have a question regarding the DayPilotBubble: I want to show the Bubble when I doubleclick on a cell for example. I have set the TimeRangeDoubleClickHandling to javascript and set the ClientObjectName of the Bubble to cellbubble. On the TimeRangeDoubleClickJavaScript I'm trying to call the 'show' function of the Bubble, but I don't know what parameters I'm supposed to pass to that function (I get an error if I supply no parameters). Is there any documentation regarding the javascript functions of the DayPilotBubble or do you have an example on how to correctly use the show function? Thanks in advance for your reply! Regards, Remco de Wit
