In angular we can make our html to have seperate sections of components which is pretty neat.

BUT.  Sometimes I cant get changeDetection to work.

e.g host html page

<section>
   <app-component-section1></app-component-section1>
</section>
<section>
   <app-component-section2></app-component-section2>
</section>

app-component-section1       html
<span>{{getTotalValue}}</span>  THIS IS NOT UPDATING when value below is changed.

app-component-section1      typescript

getTotalValue: string;

service call to get api data from sql server etc

GetTotalValue(){
   //return api data
  console.log(response.toString());  
//this value updates as expected
}

I have tried change detection but it isnt working.
