TabHost remove all content actions

I have some code for dynamically filling content for tabs. The first time it works fine, but when I want to replace the tabs (and their contents) with new content - the tabs change, but the contents of the tabs are not, how can I completely clear the TabHost and replace with other content?

TabHost tabHost = getTabHost();
Intent intent;
TabHost.TabSpec spec;

tabHost.setCurrentTab(0);
tabHost.clearAllTabs();

int idx = 0;
for(Group g: c.getGroups())
{
            intent = new Intent().setClass(this, GroupActivity.class);

            ItemLookup.createForGroup(idx).putToIntent(intent);

            spec = tabHost
                .newTabSpec("tab"+idx)
                .setIndicator(g.getTitle())
                .setContent(intent);
            tabHost.addTab(spec);
            idx++;
 }
 tabHost.setCurrentTab(0);
