To create a text inside circles in canvas, use the:

context.beginPath();

The following is the canvas:

$("#demo").on("click", "#canvas1", function(event) {
   var canvas = document.getElementById('canvas1');
   if (canvas.getContext) {
      var context = canvas.getContext("2d");
      var w = 25;
      var x = event.pageX;
      var y = Math.floor(event.pageY-$(this).offset().top);

      context.beginPath();
      context.fillStyle = "blue";
      context.arc(x, y, w/2, 0, 2 * Math.PI, false);
      context.fill();
      context = canvas.getContext("2d");

      context.font = '9pt';
      context.fillStyle = 'white';
      context.textAlign = 'center';
      context.fillText('amit', x, y+4);
   }
});
