The first and probably most important problem is that you have a domain mismatch between your data-calltoactionurl and your data-contenturl. These must be the same domain, see the data-contenturl documentation.
I believe that is your major problem, there are other problems in your example too:
You appear to be confusing two different features: app activities (aka moments) and interactive posts. Also, it looks like you are trying to do authentication, the interactive post button is also a sign-in button, notice its data-callback parameter. You wouldn't need to do a separate call to gapi.auth.init()
The most simple approach is to use the HTML button and remove the calls to gapi.interactivepost.* unless you have a dynamic application that needs to insert buttons with great control.
You didn't post the code for your JavaScript API include, ensure that it is loading the API script as https://apis.google.com/js/client:plusone.js.
Here is a correct and simplified button:
<button class="g-interactivepost"
data-clientid="xxxxxxxxxx.apps.googleusercontent.com"
data-contenturl="http://localhost:52022/Jaswanth"
data-cookiepolicy="single_host_origin"
data-calltoactionlabel="INVITE"
data-calltoactionurl="http://localhost:52022/create"
data-prefilltext="Best site EVER!"
data-callback="signinCallback"
data-requestvisibleactions="http://schemas.google.com/AddActivity"
data-scope="https://www.googleapis.com/auth/plus.login">
Tell your friends
</button>
