How can i disassociate a placed text which is associated with an element?


I simply placed a text along with an option "association with element enabled". (like i placed a text with association at the midpoint of the line). Whenever the line length is adjusted, with respect to association in midpoint, the text also positioned. 

but if i wish to move the text somewhere else. still the association is taking with line midpoint. how can i disable the text association with any element.? and how can i still maintain element length (Filed properties)

Please guide me with possible solution to resolve this.

Thanks in advance.
