title: angular2: http post not executing
body: <p>This is my first experience with angular 2. I have created a simple form and try to submit it but when http.post is executed nothing happens. There is no request made in the network tab, there is not errors.</p>
  
  <p>Here is my code:</p>
  
  <pre><code> save(model) {
          var uri = this._baseUri + "/api/contact/AddContact";
  
          let md = JSON.stringify(model);
  
          this.http.post(uri,
              JSON.stringify(md),
              {
                  headers: new Headers({
                      'Content-Type': 'application/json'
                  })
              })
             .map(res =&gt; res.json());
  
  
      }
  </code></pre>
  
  <p>I have set a breakpoint on save method and is going through there but as I said nothing happens. What am I missing?</p>
