Body Moves continuos when tap on screen
===

I want to move my body continuos when i touch screen and stop when i release touch.
I am using box2d and cocos2d and i really dont know why my code cant not perform very well.
i an using touchesBegan for sprite body movement

 

       -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
        {
            ccTime dt;
            UITouch *touch = [touches anyObject];
            CGPoint location = [touch locationInView: [touch view]];
             location=[[CCDirector sharedDirector]convertToGL:location];
            [self moveRight:dt];
            
        //    [self doWhateverYouWantToDo];
        //    [self doItWithATouch:touch];
        }
    -(void)moveRight:(ccTime)dt
    {
        CCSprite *ballright=(CCSprite *)ballbody->GetUserData();
        NSLog(@"Ball PositionX: %f",ballbody->GetPosition().x);
         NSLog(@"Ball PositionY: %f",ballbody->GetPosition().y);
        [ballright runAction:[CCMoveTo actionWithDuration:1 position:ccp(ballbody->GetPosition().x,ballbody->GetPosition().y+5*dt)]];
        
    }

So if its wrong than please tell me write logic and code
