Why texture filtering doesn't work here?

[SOLVED] Found that everything works just fine, it’s just me changing filtering mode in other place.

Hello, I trying to create RenderTarget’s in OpenGL:

	glGenFramebuffers(1, &framebuffer_id);

	glBindFramebuffer(GL_FRAMEBUFFER, framebuffer_id);

	glGenTextures(1, &framebuffer_color_channel);
	glBindTexture(GL_TEXTURE_2D, framebuffer_color_channel);
	glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, 0);

	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

	glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, framebuffer_color_channel, 0);

But when I try to render quad with framebuffer_color_channel texture on it, it looks like there is GL_NEAREST filter instead of GL_LINEAR. Is it normal? What can I do?
