Hi, 

First of all, thanks for sharing your code. 
I tried to use poly2tri with following point, but unfortunately it only returns 
1 triangle.

0.0499448 0.0749724
0.0500215 0.0749893
0.050231 0.0742612
0.049355 0.0741333
0.05 0.075

Can any one help me please???

You list of points doesn't form a simple polygon.

Go here: http://javascript.poly2tri.googlecode.com/hg/index.html
Select empty then paste your points and triangulate. You will see that edges of 
the polygon is intersecting and you got a complex polygon.

Poly2Tri is a lib to triangulate simple polygons. 

When your input is complex and you can't get around it you need to preprocess 
your data with a lib like Clipper.
