Later grab doesn't jump

I do a 2.5d game, my player jumping normally, he moves with root motion and jump with addForce.

But later a grabbing, (grab animation is play in kinematic mode, that i disable when ending the animation) i need wait some istant for can do a jump with addforce, but in this time, if i press Jump button he do animation, this animation is activable only in this mode:

     if (Input.GetKeyDown(KeyCode.Space) && canJump)
     {
         jumpCheckGround = false;
         canJump = false;
         float force = anim.GetBool("Run") ? JumpForce : JumpForce / JumpDifWalkRun;
         thisBody.AddForce(Vector3.up * force, ForceMode.Impulse);
         anim.SetTrigger("OnJump");
         anim.SetBool("Jump", true);
         canGrab = true;
     }

Why unity or i need wait this time for do a jump?
