Lightning component to clone the Oppty with products, by taking necessary changes before cloning

i have to build a Lightning component to clone the opportunities with products, i have created a component to clone the oppty with products but it is not allowing the user to change anything before cloning like standard clone button.

Could anyone help to resolve, i am not sure do we need to get the record into edit mode first or we have any other methods in lightning components, Please help me out guys if you are aware of this.
