Ionic tabs and sub views


#1

I have root page: tabs. Something like this:

Each of the tab’s root pages have sub views.
I.E: root1 -> root1-Inner-1 -> root1-Inner-2 -> root1-Inner-3

If I navigate from root1 to root1-Inner-1 or any of them, Then I go to the root2 and after click root1 tab, there is shown root1’s sub view page, instead of showing root1 page.

<ion-tabs #mainTabs color="tabsColor" >
  <ion-tab [root]="tab1Root" tabTitle="{{'ROOT1' | translate}}"></ion-tab>
  <ion-tab [root]="tab2Root" tabTitle="{{'ROOT2' | translate}}" ></ion-tab>
  <ion-tab [root]="tab3Root" tabTitle="{{'ROOT3' | translate}}"></ion-tab>
</ion-tabs>

How can I make, that after tapping on tab title, always show it’s root page?
