triangle Mesh Collsisions using btGImpactImpactshape

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?
I was having some problems with the scheme of collision detection shown below. 
The collision detection between two meshes does n't get detected even when the 
two triangular meshes are actually colliding. Do you know what I am doing 
wrong? I am getting 90 % of the time correct but sometime bullet doesn't detect 
collision between two triangular meshes

Both meshes I am using btGImpactMeshShape  to construct it.

What version of the product are you using? On what operating system?
2.80

Please provide any additional information below.
