Action bar title doesn't show when set dynamically

See original GitHub issue

Hi guys,

I recently migrated my {N} + Angular2 app to the 3.0 version of Nativescript, and it globally runs pretty smoothly, yet I encountered a strange behaviour that kind of annoys me.

Platform: I tried it on Android only, I didn’t have the time yet to try it on iOs

Version:

nativescript 3.1.2
tns core modules 3.1.0
tns android 3.1.1

Issue:

When I use a static ActionBar, it works just fine, the title shows so does the navigation button.

<ActionBar  width="100%" title="Action Bar title"> 

       <NavigationButton icon="res://ic_arrow_back_white_24"  (tap)="goBack()">                          
       </NavigationButton>

</ActionBar>

However, when I dynamically set the ActionBar title with angular, the UI doesn’t seem to be refreshing, and the title doesn’t show:

<ActionBar  width="100%" [title]="getActionBarTitle()"> 

       <NavigationButton icon="res://ic_arrow_back_white_24"  (tap)="goBack()">                          
       </NavigationButton>

</ActionBar>

The same problem occurs when I dynamically display (or not) certain elements of the action bar, even if the title is static:

<ActionBar  width="100%" title="Action Bar title"> 

       <NavigationButton icon="res://ic_arrow_back_white_24"  (tap)="goBack()">                          
       </NavigationButton>

       <ActionItem icon="res://ic_menu_white_24" text="Do something"  (tap)="doSomething()" *ngIf="isAndroid">                          
       </ActionItem>

</ActionBar>

I remember encountering the same kind of issue a long time ago in an old version of {N} while the Telerik dev team was trying to catch up with the daily releases of Angular 😃 so maybe it is a known issue, would you tell me if it is the case, and if there is a workaround ?

Thanks
