I created a wireframe rasterizer state and it works if I set it everytime I render an object. But if I initialized it one time next frame it resets to default rasterizer state. Is this the default behaviour or there is something wrong with my code?

Yeah that was the first thing I have checked and there is only one place that I call RSSetState function. So here is how I set it. And as I said this works if I set it everytime before I call draw for my object.

D3D11_RASTERIZER_DESC rd;
	ZeroMemory(&rd, sizeof(rd));
	rd.AntialiasedLineEnable = false;
	rd.CullMode = D3D11_CULL_BACK;
	rd.DepthBias = 0;
	rd.DepthBiasClamp = 0.0f;
	rd.DepthClipEnable = true;
	rd.FillMode = D3D11_FILL_WIREFRAME;
	rd.FrontCounterClockwise = false;
	rd.MultisampleEnable = false;
	rd.ScissorEnable = false;
	rd.SlopeScaledDepthBias = 0.0f;

	d3dDevice->CreateRasterizerState(&rd, &rasterizerStateWireFrame);
	deviceContex->RSSetState(rasterizerStateWireFrame);

It was a stupid mistake. I found it when I checked the debugger on VS2012. I was using DirectXTK to write some stuff to screen. And it was changing the rasterizer state. Thanks for the help.
