How do I create multiple map and render it at two places in view about googlmapper HOT 2 CLOSED

Hi, multiple maps can be achieved like this:

Mapper::map(53.381128999999990000, -1.470085000000040000);
Mapper::map(52.381128999999990000, -1.570085000000040000);
Mapper::map(51.381128999999990000, -1.670085000000040000);

Then the method render accepts an input parameter of a zero based key for each of the maps:

Mapper::render(0);
Mapper::render(1);
Mapper::render(2);

from googlmapper.

Ok I can create multiple maps in one page but it doesnt work when I put them in tabs. I am using bootstrap tabs where different tab panel will have different map. But only first one renders and others just remain blank (gray background with google logo at bottom-left).

My situation is like this I need to display upcoming event and past event and toggle between them.
Is there any way I can just toggle the markers with a button click because I am using same map.
