title: trigger function when mobx observable is changed
body: <p>I currently trying to create a function which should be triggered in my react component when my observable in my store is changed (i'm using mobx).</p>
  
  <p>this is my store =></p>
  
  <pre><code>class myStore{
  @observable myVariable
  }
  </code></pre>
  
  <p>this is my react component =></p>
  
  <pre><code>@observer
  export default class MyComponent etends React.component {
  
      render(){
      //rendering stuff here
      }
  
      someFunctionTriggeredByObservableChanged(){   // maybe a intercept or observe from mobx ?
      }
  
  }
  </code></pre>
  
  <p>I was wondering if i could use maybe intercept or observe from mobx directly in my react component ?</p>
  
  <p>Thanks,</p>
