How to get the pivot object by jquery selector

I want to get the flexmonster pivot object by ID.
For e.g. 
I crate the pivot using below code

var pivot = $("#pivotContainer_"+uniqeId).flexmonster({
 report: {
 dataSource: { filename: "data.csv" } }, 
licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX" }
);

Now later in the code I want to get this object by the ID that I have which is "pivotContainer_"+uniqeId,  

$(("#pivotContainer_"+uniqeId).flexmonster()

I don't want to use pivot variable which is defined while creating the pivot.
