title: BehaviorSubject Services for components interaction - Property used before its initialized
body: <p>I want to use form data from one component to another, in first component I'm using <code>(ngModel)</code> and with <code>BehaviorSubject</code> I'm storing my data in <code>services</code>.</p>
  <p>Now, I'm <code>subscribing</code> to those services in another component and getting data in local variables. Till here, it's working fine and I'm able to get the data but only when I put that values in Model it says <code>Property 'someName' is used before its initialization.ts(2729)</code></p>
  <p>I want to put this data in Model and call an post API based on this, what is the right way to do?</p>
