QlikSense Mashup Selection Bar

[prasoon1852]

I am creating mashup in QlikSense. I have included the QlikSense selection bar in my code.

<div id="CurrentSelections" class="qvobjects"></div>

My single web page has 3 different apps and to get the selection and remove it i have used the code -

app1.getObject('CurrentSelections','CurrentSelections');

But the problem is it works for only one object. If i select any object from app2 then i can't deselect the selected value from selection bar.

How can i make selection bar to automatically understand the app1/app2/app3 based on user selection and give them choice to deselect their selected values ?
