title: passing parameters in (click)="fun(param)" in ionic-angular2
body: <p>I'm having button in login.html file. </p>
  
  <pre><code>&lt;button  data-sql="SELECT ep.PROJECTID,ep.PROJECTNAME FROM euser eu,eproject 
  ep WHERE eu.projectid = ep.projectid AND eu.username = :USERNAME" 
  data-sqlparams="USERNAME" data-logintype="otp" ng-click="customLogin()"&gt; 
  
  Login   
  
  &lt;/button&gt;
  </code></pre>
  
  <p>And Here my doubt is, Can i pass data-sql,data-params and data-logintype to login.ts file thru ng-click? </p>
